UE5 crash and unable to open file

CharlieM92911 · May 13, 2022, 3:30pm

Hey all! I was setting up my file to be packaged for Oculus Quest and I kept having a greyed out “VR preview” and in a forum it said to enable “instanced stereo”. Once I did that it had me restart but now I am unable to open my project without crashing. Any ideas how to fix this and or to change that setting? I am hoping I didn’t fully lose the project…thank you for any help!

Here is what the crash report says:

Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Runtime\RHI\Private\PipelineStateCache.cpp] [Line: 144] Shader compilation failures are Fatal.

You can go into your config folder inside the project and in the DefaultEngine.ini change / remove the InstancedStereo setting and save the *.ini file. Delete this line “vr.InstancedStereo=True”

€dit: I remember that there was a problem with instanced stereo and something else which creates crashes when using materials. Have a look for it in the forum.

THANK YOU - this fixed it

How do I fix this on a Mac?

Fatal error: [File:/Users/build/Build/++UE5/Sync/Engine/Source/Runtime/RHI/Private/PipelineStateCache.cpp] [Line: 144] Shader compilation failures are Fatal.

I don’t have the DefaultGameEngine.ini file.

Hey @Yo_Ung_Ming1 ,
when you create a project it will create different folders inside this project folder. When you go to your project (inside your explorer, not Unreal) which folders are there? Do you have a Config folder?

Yo_Ung_Ming1 · September 28, 2022, 3:02pm

Yes, a folder with:
DefaultEditor.ini
DefaultEditorPerProjectUserSettings.ini
DefaultEngine.ini
DefaultGame.ini
DefaultInput.ini

L1z4rD89 · September 28, 2022, 3:15pm

Oh, now I see it: DefaultEngine.ini, inside this file there is “vr.InstancedStereo=True”

Yo_Ung_Ming1 · September 28, 2022, 3:20pm

Yes, I deleted it and saved it.
But nothing changes.

I still got the following:

Copy your project folder, delete everything except CONFIG, CONTENT and your *.UPROJECT file. Then try again.

Alternative:

Upload your project
Tell us what you changed in your project or it is a new one.

Yo_Ung_Ming1 · September 29, 2022, 6:11am

It’s a new one, nothing changed.
I completely reinstalled UE 5.0.3 and the Quixel Bridge plugin.

In the settings “privacy and security” I needed to allow Macos to open node.bifrost.app

My project shuts down when I am using my mouse to navigate in the viewport.

Can you create a new folder, paste these files inside it and test it?

That is your project with all settings reset, no plugin, no project settings (except your input)

Yo_Ung_Ming1 · September 30, 2022, 12:59pm

I reinstalled Monterey, Epic Games Launcher, UE5 + bridge and Xcode.**

Now it seems to work all correctly.

So I don’t know if your adjustments are OK.

Thanks anyway!
