It started to happen to me too. I'm pretty sure it's either the nVidia driver version, or the geforce experience (I don't know what of this 2 because I updated both at the same time). Try rolling back to a older driver or uninstalling geforce experience.

 

I have this happening across four different driver versions and geforce experience has never been installed (since it's just spyware).

 

I had this issue today. I also submitted a bug report earlier but in short, it was occurring when launching any project (existing or new) in 2020 & 2021 after updating NVIDIA drivers to the newest version, (as well as various other versions on the NVIDIA site I installed after that to attempt to fix it). Using Windows 8.1, NVIDIA GeForce GTX 860M, also have an Intel(R) HD Graphics 4600. I tried disabling the Intel one in the Device Manager and while it stopped the error, the scene/game in the Unity editor was still super slow (But fine when playing games or launching a build from one of my projects).

In case it helps anyone else, I uninstalled the NVIDIA driver through the Control Panel / Programs And Features and restarted the PC. It seemingly reinstalled some older versions (possibly previous ones I had installed? Or perhaps windows chose specific stable ones, idk). It didn't work the first time but I did the same thing again and it installed an even older one (385.46). Perhaps not ideal to use older drivers, but it has fixed the error and lets me continue using Unity at least. Maybe this method will work for others too.

 

Was happening once in a while before, but since I updated to latest nvidia drivers it happens constantly after 30 mins or so of usage.

Then I used DDU to completely remove old drivers before installing new ones and so far I didn't get another crash.

Unity 2020.3.1 On URP 10.3.2

Windows 10 Pro
Ryzen 5600x
GeForce RTX 3070

 

That worked for me .. Thank you so much

 

It worked for me too but I don't feel comfortable using an experimental api. Using d3d12 also causes the game window to have severe tearing, regardless of framerate or vsync settings.

 

hi, try this, seems to work for me.

Edit: again crashed...

crashed sometimes after 5mn in the timeline
the same scene don't crash at work on another pc (GTX 1080)

it's clearly a problem with RTX Card..

 

Mine's crashing with the same error at the end of a Windows build (if I have the scene open), if I build while in a blank scene it doesn't seem to crash.

AMD 5900HX / RTX 3080 Mobile 16 GB VRAM / 32 GB RAM Lenovo Laptop, Unity 2020.3.12, URP, Mono build.

Running in hybrid mode (nvidia optimus), but Unity is running on the dGPU. Need to try switching to dGPU only mode to see if its fixes it.

The build actually seems to come out just fine, just the editor crashes at the end.

I've built the same scene to android just fine many times without ever crashing.

Scene is mildly complex (150,000 triangles maybe, lots of shaders), but not so crazy it can run decent on my android phone.

Edit: It still happens, but seemingly much more rare.

 

I didn't see chip creep mentioned here.. it's caused by repeated expansion and contraction due to temperature variation - over time, chips can eventually work their way loose.. then you get issues like these (and worse). However.. slim chance of this being the reason if your system is new, as it typically takes years to happen.

 

I may have just found a fix for my case: I had previously installed NVIDIA Omniverse to check out some graphics demos, and I uninstalled it... However, some part of it was still running (found Omniverse System Monitor in my task tray). Apparently its a common problem, and nvidia even made a tool to remove it:

https://docs.omniverse.nvidia.com/prod_launcher/prod_utilities/cleanup-tool.html.

After running that tool, Omniverse system monitor is gone and I have made 3 builds in a row without crashing, with the scene open. (First 3 times without crashes all day!).

Will update if this didn't really fix it, thought I'd share it as it may help someone.

 

hey, i found a solution that worked for me.
copy the
D3Dcompiler_47.dll from the directory C:\Program Files\Unity\Hub\Editor\YOUR UNITY VERSION\Editor\Data\Tools
and paste it in C:\Program Files\Unity\Hub\Editor\YOUR UNITY VERSION\Editor\
this worked for me

 

I've been getting this error a lot today and I can easily reconstruct it. It's when I'm using the HPSXRP (or Haunted PSX Render Pipeline) package. I was only testing the shader to see how it works so I added a cube and a plane. In order for lighting to work on the objects however I need to add a custom material using the PSX shader onto the cube or plane to see it properly.

Not long after (about 5-10 seconds) Unity crashes with the D3D compiler error and after reading some of the previous comments here it might be related to shaders, especially since I have only two objects in my entire scene. I've tried a few of the solutions and nothing has worked for me so far.

I have submitted a crash report to Unity so will be interesting to see what comes of it but in case it is still needed here are my specs. Let's hope there is a fix available for this!

Windows 10 Home
Radeon RX 570
Intel i5-2500K @ 3.30GHz
2x8gb DDR 1600MHz

 

I've shared this with the developer of the HPSXRP. I was also just having this issue today, never experienced it before. He's going to be looking into it to see if it's an issue with the pipeline or not

 

for anyone else still having this problem, i just had to re-install my nvidia geforce drivers and that fixed the issue

 

That worked for me! Thanks!
I'm using very heavy compute shaders for offline rendering and it clearly needed more than 2 seconds to render LOL!

PS: before that I had my PC shutting down randomly because the UPS was not up to par with the spikes in current consumption and had to plug the PC directly to the wall instead...
My 3090 is breathing fire right now

 

Hi, i solved it by closing another desktop opened and just leaving 1. (Windows+TAB key)

 

Having this issue with 2021.1.17f. Once it happens, only Windows restart fixes it. It's unusable. Having 3080 RTX, latest drivers

 

Just reset my computer and i still get the error what is going on unity

 

Also running into this issue.

Repros consistently upon resize of the Scene View. It happens instantaneously upon resize, it does not take 2 seconds (as noted above).

For me is directly correlated with an series of models made in Blender and exported as an FBX for use in Unity. The Models are pretty simple.

I've tried deleting the library folder, doesn't help.

@Soner-Sen -- If the root cause is indeed a "complex" or "invalid" mesh, then surly Unity can check for that? At a minimum is there not a utility addon / package you guys could share out for us to better understand the source of the issue? Ideally calling out the mesh that has the issue so we can go fix it without resorting to brute force trial and error?

Specs:
Windows 10
16 gb RAM
RTX 2080
i7-8700 @ 3.2Ghz

 

Have you tried this fix?
Maybe it's not related, but it's worth a shot, as It will not hurt anyway.

 

@atomicjoe
No I haven't. Appreciate you flagging it for me though. However, I really don't think we should have to hack around this kind of stuff.

Unity is a product I pay for. Integration with Blender is something they call out as a first class feature. Crashing consistently because I have a "complex mesh" means there is a reproducible bug here, this thread further supports that. Unity can and should take the time to reply to us and address the issue. It is not okay that technical support is outsourced to the community.

 

This much is completely true.
If you are a pro user, don't even bother posting on the forums, just fill a bug report and include a repro project with the mesh that is causing you problems. Pro users bug reports are checked out quickly, I can attest that.
You can also email the pro user success advisors, they are eager to help and could speed this up for you.

 

Thanks, I'll give that a shot.

 

@Tautvydas-Zilys That is the worst reply I have gotten from a customer engagement representative in years. Very sad to see this from Unity.

 

Xbox game bar showed me that my machine was not running DX12 correctly so I updated my OS to the latest build and it fixed my problem. I had tried everything previously. Reinstalling my OS, Unity, Drivers, Registery Edits, and I only have a dedicated GPU so integrated wasnt a problem. But it sounded like an OS issue. I would make sure your up to date with the latest Build as just getting updates wont do it. I had to migrate to 20H2.

Edit: it didnt fix the issue. But at least it white screens so I can still save my scene / changes before closing.
I am out of ideas.
Also specs:
AMD 3900X
RTX 2080 Ti
Asus X570-Pro MB
Ram: 32GB
Windows 10 - 20h2

 

If it helps:

Getting this up to a few times each day, often when Unity is idling and I'm working in something else. My whole computer freezes up too, sometimes indefinitely instead of showing the error; but it appears to be the same problem.

I do tend to have a lot of programs open at once, but Unity is always the only one that crashes.

Windows 10 Pro 21H1 19045.1165
Intel i9-11900KF @ 3.50GHz
32 GB RAM
NVIDIA GeForce RTX 3070

Unity 2020.3.1f1
URP

Doesn't seem like others on my team are seeing this, though I seem to remember seeing it on other computers I've had (less frequently).

 

Does the error always come because maybe the RAM memory too big?

 

I have the same issue today trying to convert one of my projects to 2020.3.18f1 (not tried with a new project though)

I had this issue on some PCs with lesser GPUs before, but now appears on my laptop with Nvidia 1050GTX and Unity is unusable !!

I really dont know what to do with this, as cant work on new Unity at all now

This was never an issue in 2019.4 Unity, so there must have been something extremely wrong in making the new Unity versions, please fix asap these errors so we can work.

EDIT: Found some solution, will try now as seems i do miss the whole Tools folder, maybe be a HUb problem afterall that did not do the install properly

Public Service Announcement:
FILL ACTUAL BUG REPORTS IF YOU ENCOUNTER A BUG!
(Help menu -> Report a Bug...)

Complaining in the forums will not get it fixed. The forums are for discussing issues with other users (or for screaming into the void out of frustration, we do that too ) but if you find an actual bug, send Unity Tech a bug report with a repro project. It's the ONLY way you will get your problems solved (hopefully).

Once you know it's an actual bug and that you have filled a bug report with a repro project, THEN you can put up the pressure by complaining in the forum, with an actual link to your bug report so that we can all upvote it.

 

It only happens on higher lightmap settings on Progressive GPU (preview).
Progressive CPU works always.

-Updated graphics card driver. didn't work.
-Bought a powered USB hub to see if my power is not enough but didn't resolve.
*I thought the entire machine crashes but noticed only the screens go out, sound works.

My specs---
Window 10
Ryzen 9 3950x 16 Core

Crashes on Unity 2019 through 2020.3.18 so far.

Did you try the GPU timeout fix from earlier in the thread?

 

I was able to file a bug report and Unity Helped get it solved for me at least so far. Its been several days and no issues.
They had me set my NVidia control panel to restore defaults, the only option I had changed was Enabling G-Sync for windowed and Full Screen Mode. So after disabling g-sync for windowed mode everything seems to be good.
Give it a try?

 

Enabling GPU instancing for a terrain detail object somehow fixed it for me

 

replying here in case this helps ANYONE else... GPU instancing on a complex terrain object thats being lit by the gpu, G SYNC monitor and gpu using g sync while using unity being turned OFF from ON for "Low Latency Mode" within Nvidia control panel have seemed to fix my "hold on, busy..." progress bars, and HORRIBLE performance with the editor.

full post here Lots of busy... Hold on.... etc?

 

Removing Library folder worked to me. However it's not really nice solution as the Library folder holds some required temp data to your timeline or shaders. At least it did for me.

PC Setup

Nvidia RTX 2070 S
Windows 10 Pro
Intel Core i9 10900K 3.70GHz
2-Displays, both 1920x1080
using Unity 2020.3.19f1

 

In my case it has something to do with nvidia drivers. I haven't checked all of them, but it seems like the erros starts to appear at ~450.
It crashed on 456.71, 471.68, 471.96, 466.47, 472.12.
It works on 446.14. It also worked on 440.something.
Specs:
Windows 8.1
Geforce GTX 960m
Intel Core i7-4720HQ
8gb ram

EDIT: forgot to mention - crashed immediately on start.

 

It appears that my issue was caused by my PCI-e 3.0 Riser Cable since I run GF3080 with a B550 Mainboard and PCI-e 4.0. Ever since I threw this one out, the issue hasn't reoccurred.

 

Same problem.
Nvidia GTX 850m, Driver 472.12
Intel Core i7-4700HQ 2.40 GHz
Windows 8.1 x64
Tried installing different Unity3D versions but to no avail.
The Engine doesn't even open up. The crash happens right after loading a project.
In 2019.4.31f1 version, the window opens and doesn't crash, but it stops showing anything after the hierarchy window.

Unity used to work for me just fine. I can guess it's the driver update, but that's just sad. I can't roll back, I also use Unreal engine on my computer, and I'm pretty sure it works well because I have an updated driver. Will send this to a bug reports as well.

 

Tried to deactivate the Intel Graphics Card Driver, and it worked. Does anyone have another solution? :/

 

Happens on Unity 2020.3.16f1 (64-bit) with the latest NVIDIA Drivers.

I tried to delete the library folder and worked.

so this is a unity issue, not a driver one. also happened for some reason on an older project without making any update to unity.

 

Hi !
First step disable D3d12 in the build settings.
Second step open a simple scenario when compiling.
it worked with me.

 

Hi!

I have been having this problem for a while now(longer then a year across multiple computers), and usually it would lock my pc entirely. and no error to be found anywhere. these freezes only seem to happen when using unity. and I cant seem to find a way to replicate them.
sometimes they happen multiple times a day, then nothing for weeks.

specs:

windows 10 (21H1, os build 19043.1348)
AMD Ryzen 7 5800X
NVIDIA RTX 3070 (driver version: 472.12)
2x 2560x1440 screens with HDR

its not he latest driver version (currently updating). but I doubt this will fix it
this time however the freeze did not lock op my pc, and I managed to find an error in event viewer
