Crash: d3d11.dll caused an Access Violation (0xc0000005) in module d3d11.dll at 0033:ef656f40.

I'm not really getting a good error on this one, so its hard to track down whats going on. I can repro it almost 100% in a complex scene but its way to big to upload in the bug report. Any idea what could cause this?

Yes. They are updated to the latest.

 

Also this is new in 5.4. I never had this crash before.

 

I think you missed my post where I said I had the latest drivers and posted my DXdiag. two up. As you can see I have 372.70, the latest driver. Also I did update the drivers after getting the crash, but no luck.

I've narrowed it down to this line of code: UnityEngine.Object.Destroy(this);

Maybe a race condition in 5.4s multithreading?


What can I do to help you guys track this down?

My project cannot be uploaded, its huge and its hard to create a test project for it as the error isn't really giving me anything to go by. What combination of things am I doing that causes this crash... no clue. That said everything I'm doing causes no errors if I remove that one line of code. I've tested this many many times.

I don't know what to rip out and what to keep. Its happening a lot though, about 50% of the time when an enemy dies. Less often in a less complex scene.

-I have friends at your Seattle office, I'd even be willing to cart in one of our teams setups so they can take a look if that's what is necessary. I was avoiding bothering them directly as I though you all might have more insight as to what would cause this error.

-I'd be willing to have an engineer connect remotely.

Let me know what the next steps should be. At this point though we are unable to test our game in 5.4 and 5.3 has other issues that were blocking us.

 

(please read the previous post as well)
Also,
if it helps. The crash happens when calling UnityEngine.Object.Destroy on a ScriptableObject.

 

I did send in the bug report.

That said most the time I send in bugs it take many months to fix, and we are unable to wait that long.

The first thing I did is read through the error logs and such. But this: "d3d11.dll caused an Access Violation (0xc0000005)" is not something I can fix without more information or the ability to debug. It could be anything.

 

Thanks Tomas,
(Case 831709)

Let me know if there is anything I can do to help. I can even give access to our SVN if that would help. Thanks.

 

Thanks for the help, It is very much appreciated.

I wasn't sure how to update a previous case number. I submitted a new one with (Case 831709) in the subject line. It went in as Case 832791


I have this on the crash log file:
</SystemInformation><Exception>System.NullReferenceException: Object reference not set to an instance of an object.
at Mono.Addins.ExtensionNode.get_ChildNodes() in c:\buildslave\monodevelop\build\monodevelop\main\external\mono-addins\Mono.Addins\Mono.Addins\ExtensionNode.cs:line 224</Exception></CrashLog>


I got a much better error log. It looks like its trying to allocate a whole tone of memory? Not sure what could possibly be trying to allocate that much memory.

As a note:
Probably not related but the first crash I got GUI Score was the last thing that was called before the crash.

So I tried commenting it out. it was:

Code (csharp):

1.  
2. Debug.Log("Score changed from [" + lastValue + "] to [" + value + "]");
3.  

The next crash I got was just after GUIScore.cs Line: 36. which is:

Code (csharp):

1.  
2. Debug.Log(message);
3.

Understood. I'll try to rip out what I can and upload something. It might be a huge upload. If it ends up being too big I'll contact some peeps at Unity Seattle and bring my box in. I'll let you know when I have something up.

Thanks again for helping with this.

P.s. is there a good way to update an existing bug so I'm not spamming you guys with dupes?

 

Too late for this time but I'll know next time thanks!

 

We spent a night ripping the project down to size and are uploading a repro to QA now. It went in as Case 833096, the project is uploading to a cloud you can grab it from soon.

 

This was fixed in the latest patch. Thanks for the help!

 

I just installed unity 5.6.0f3, got same crash with crash in d3d11.dll. Where to get latest patch?

 

Hi !
Got the same editor crash with 5.6.0f3 and 5.6.1f1.
Interested on how you solved it too.
Thx

 

Got the same editor crash with 5.6.0f3 and 5.6.1f1.

Same here... It rarely happens when leaving a scene, therefore I think it has something to do with the Destroy function

 

I recently started getting this. I am curious as to how this was solved. I am currently using editor 5.6.1f1.

It usually happens when I exit play mode, it hangs before crashing. I also suspect it has to do with the destroy function.

 

Hi,

I'm getting the same error but on Unity startup.
I get the open/new project screen but after that it crashes. with that error in the logs:

d3d11.dll caused an Access Violation (0xc0000005)

I would realy like to get Unity going lol

 

Someone playing my game has had the exact same problem. I am using Unity 5.6.2f1. I cannot replicate this error myself on any of my computers. The player is using Windows 7 x64, if that is an important factor.

From their description, I believe it occurs when an Object is Destroyed. It does not appear to take place on loading of scenes.

Could Unity please advise on if there is anything I can do, or if there is going to be a hotfix for this Unity 5-based problem in the future?

 

Just to chime in on this and sorry for necro, I also get a crash with this error when calling Destroy(), Clear(), or Stop() on particles or certain objects using the toon/lit shader.

Pastebin of error.log here: https://pastebin.com/giC16MLH

 

I always get this crash and isn't fixed in .2 or .3. Always running latest drivers.

d3d11.dll caused an Access Violation (0xc0000005)

in module d3d11.dll at 0033:2857bf9b.

(Rename extension to .dmp)

-Error reports seem to take forever to compile.

 

Hello, same here with 2017.2.0f3

 

If you can reproduce the issue, could you please submit a bug-report following the advice given in this document?

Unity's Bug Reporter tool collects various information about your system, such as driver versions, log files, etc that helps them to identify the problem.

Using the bug-reporter is an important step, because it makes sure the report is in Unity Technologies bug-tracking pipeline. Using the forum is often used to add attention to an existing issue, but does not replace submitting a bug-report.

It's from advantage to attach a project to the bug-report that UT can use to reproduce the issue and test their fix against, this is especially important for crash-bugs. If the player crashes, it normally creates a "crashes" directory next to its .exe file that contains a crash.dmp file. It proved useful to attach this crash.dmp file to the bug-report as well.

The easier an issue can be reproduced by QA, the more likely it is to get forwarded to a developer, who might or might not work on a bug-fix for that at some point.

After you submitted the bug-report, you receive a confirmation email with a Case number. UT often asks us to post the Case number in the forum thread, which allows them to find that bug-report if they look at your post.

Following these steps will increase the chance that UT is looking at the issue tremendously.

 

Folks, if you open your .dmp files with Visual Studio 2015/2017, you'll be able to produce stack traces that are more easily identifiable/readable for the Unity folks and other users. You can copy/paste those with your forum posts. Finding .pdb's in your local Unity installation folders and adding those paths to your symbol search path (leaving the Microsoft Symbol Server path), will help as well.

Anecdotally... anyone on Windows 7 (I read above) and having d3d11 issues: I believe Microsoft said they were not fixing d3d11 on DX11, but you should check that. I've experienced a variety of d3d11 crashes (reporting them all) on Unity 2017 and older Unity versions, even on Win10. Most are on my older NVidia-based gfx card. Note also that NVidia's GeForce Experience overlay functionality also injects itself into the mix. I've notice some quality problems with it as well, but it seems to be stabilizing. Generally, I've been shutting it off.

 

I have tried to send an error report on a few occasions but it seemed to take forever to compile. I am running windows 10 and a recent gfx card (Geforce GTX 1060). The Geforce Experience overlay does appear every now and then, could try disabling it.

For now, anyone coming here looking for a solution, I have found that forcing unity's ui to run in opengl mode works flawlessly and hasn't crashed once no errors or tradeoffs, performance has increased, no more UI lag.

Just add -force-opengl to the end of your unity shortcut:

 

I have submitted a bug report with the same error. I don't think this has to do with Geforce, as I am getting this error on both my machines, and one has a Geforce GTX card and the other has an AMD Radeon card.

 

This helped me!
Did a fresh install and suddenly i got this error, tried to install old version but dident work, also tried to close almost all programs running in background and also updated drivers and did a windows update, still got the same error but after trying D:\Apps\Unity2017.3\Editor\Unity.exe -force-opengl it worked

Thanks alot!!

 

Sure - you take DX out of the execution path, and you aren't going to hit the problem. But there's still a problem in the common code path here.

I confirmed for my old GeForce Gtx 285, that support is frozen (even on Win10) and the d3d11.dll version is dated/stuck. It would be surprising to me that NVidia would will address the problem for such an old driver set.

 

You're welcome buddy, I'm glad this works for you too as it was giving me a headache!

 

Totally agree, this is simply a workaround as this has been happening to me across so many unity updates without a fix.

 

I got this from Unity today:

This is for version: Unity 2018.1.0b2

 

Have you tried it, can confirm with safety? Just downloaded it and building my project - hopefully they fixed i!

 

The new beta doesn't work for me yet, first have to wait until all my plug-ins are updated to work with it before I can test. I tried it and just got loads and loads of errors and the game wouldn't run.

 

if any of you are stilling having problem, Update your Java!

 

Getting
UnityPlayer.dll caused an Access Violation (0xc0000005)
in module UnityPlayer.dll at 0023:68b6cb7f. whenever I try to build a project? Whats the solution to this?

 

doesn't help

 

Still crashy Also this is effecting all Unity apps not just the ones I've made.

 

Is anyone still experiencing this issue after updating to 2018.1.0b2 or higher?

 

Has anyone come across any more fixes? I'm working on the Unity 2017.3.0f3 and having this issue.

I've updated both my Java and Graphics card to the latest version

 

Probably not much help to anyone here, but my experience of this crash in the past was fixed by disabling the "Graphics Jobs (Experimental)" option in the Player settings.

I have a bad habit of enabling this option thinking I might gain an extra fps here or there and then forget I enabled it.

After many hours scratching my head wondering why the build is suddenly crashing when it wasn't before, it dawns on me...

Obviously if you haven't got this option selected anyway then this is of no help.

 

I'm getting it on 2017.4.0f1. I have a case open with Unity but no response.​

 

There are possibly two separate issues here. Access Violation (0xc0000005) errors are memory related, however, the first one reported by the OP is stemming from DX11 (d3d11.dll) and the other from the engine itself (UnityPlayer.dll).

For those with the latter (UnityPlayer.dll) you may find a fix in versions 2018.1.0b11, 2017.4.1f1, 2017.2.2p2, 2017.1.3p3 or 5.6.5p3; according to this post https://stackoverflow.com/a/49703357/9481503

For those with the DX11 (d3d11.dll) issue, I believe it's a GPU resource bug in at least one of Unity's rendering pipelines. After many (many) hours pulling my project apart I've (somewhat unexpectedly) discovered that switching from Deferred to Forward rendering has alleviated the crashing. Although not ideal (I'm losing >25% FPS in Forward), it may be workable for you.

I do hope Unity will respond to the bug reports. Just googling "d3d11.dll caused an Access Violation (0xc0000005)" will return plenty of results related to Unity...
