Unreal keeps crashing when trying to do stuff in material, blueprints, etc.

Hello everyone,

I am currently in an state where I can’t literally edit my game / project in any way. Whenever I try editing materials, coding with Blueprints, etc., my project crashes instantly. I changed the RHI to DX11 to not experience any lag in editor / executable, though still getting the same issue.

I also see that it gets stuck at 45%, compiling shaders (64), though it gives up, and I get a “heads-up” saying

LANDSCAPE: 64 Actors need to be rebuilt.

in a specific scene (default scene).

Crash log:

Fatal error: [File:D:\build\++UE5\Sync\Engine\Source\Runtime\RHICore\Public\RHICoreShader.h] [Line: 147] Uniform buffer bound to slot 4 is not what the shader expected: Bound : Uniform Buffer[Material] with Hash[0x05780908] Expected : Uniform Buffer[Material] with Hash[0x05880908] Shader Name : <unknown> Layout CB Size : 112 Layout Num Resources : 4 Resource Types : 5 8 8 8

Is there a way to fix it? Or at-least save some stuff?

any fix ?

我遇到了你和一样的问题,请问你有解决吗

Hi,

I am not sure if you figure it out, but just in case: I had a similar error using some imported meshes from and old project. Disabling nanite in the static meshes remove the crash for me.
