I’m trying to open my small project on a new PC and a new windows installation and I keep getting this crash error after shader compilation and the project does not open.
Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\ShaderCompiler\ShaderCompiler.cpp] [Line: 4668] Invalid ray tracing callable shader parameter ‘bStaticallyShadowed’. Only uniform buffers and loose data parameters are supported. Failed to compile default material /Engine/EngineMaterials/DefaultDeferredDecalMaterial.DefaultDeferredDecalMaterial!
If I switch to my old windows on my other SSD, I can open it with the new hardware and there are no problems.
It sounds like you need to do a repair or a fresh install! It’s saying the compiler (that is part of the engine\source so it comes WITH UE5) is throwing the error, so it’s not something within your project… Hopefully. Unless you altered it, but unless you had it SHOW ENGINE CONTENT you shouldn’t have been able to do so.
That being said, with it being a new windows installation, if it’s windows 11 there are still issues with W11.
Another thing to do: Make sure your Microsoft Visual Studio is up to date!!
