Unity crashes after update from DirectX11 to DirectX12 and won't open project

I tried to open my project in two 2020 versions of unity and it won't do it. I cannot open my project now... and Unity won't even let me to try and open a new one (and fix the HD Render Pipline wizard), it crashes again... I cannot even report the problem, it won't send it.

 

Check the editor log file for more information on what might be causing the crash.

 

Which exact version of 2020?
Have you tried different options 2020 installation?
What about 2019?

 

Try launching it with --force-d3d11 or --force-glcore command line switch.

Cant you just revert changes in git? or stash them?

 

It looks the problem is not about git repo, or project itself, but about Unity conflicting with DX12, by what OP is describing.

 

Anyone ever find a solution to this?

 

Given that the OP never provided any additional information about their crashes, Unity version, and I've been unable to reproduce the bug in the 2020 versions I've tested, I'm not sure what we'd even be trying to solve.

 

Is DX12 still in experimental? haha DX13 will be available before Unity get it stable :O

edit: i just tried on 2020.2.0 I can switch. But the game is just black when running in editor. VR game using OpenVR with latest XR management.

I can also change back to DX11 and the game works again

edit: btw the switch is really fast on our 60 gig project (not included library). So they have improved something there

The first one is the issue I reported, they acknowledged and said they are aware of the issue, but have not fixed it yet. Whether they will make an effort to fix it remains to be seen.

 

I had to start it with ----force-d3d12, so I had to change the 11 in the command line to 12. That had helped me.

After that u need to do:

Go to Edit > Project Settings > Player settings > Other Settings. In the Rendering section, disable the Auto Graphics API for a platform (Windows/Mac/Linux) option. Click + to select DirectX11 or DirectX12 from the list of the supported Graphic APIs. For more information, see Graphics API support.

 

hi i came to the assumption that UNITY is not powerful enough to handle dx12 just yet, that is why its experimental. unity required a major update to support not more CPU and RAM, but to better utilize other API like unreal engine does. UNITY alone has a crashing problem due to memory leaks at times on a stable project i can get random hangs at 100% 24 threads and or a full 24gb ram out of 48 at times for no reason in dx11 so dx12 will be worse, they need to fix FSR, DLSS and add a true dx12 support i been ready to fully go ray tracing on my projects
