Hi, I have the same issue. Investigating it right now.
Progress so far:
The exact same project and source built engine works on a different machine that uses visual studio 2019 instead of 2017.
installed latest driver update -> no change.
deleted all generated code and stuff from my project -> no change
[2020.05.25-14.11.45:306] 0]LogShaderCompilers: Warning: 0 Shader compiler errors compiling WorldGridMaterial for platform PCD3D_SM5:
[2020.05.25-14.11.45:306] 0]LogShaderCompilers: Warning: D3DCompile exception
Fatal error: [File:X:/Unreal/UnrealEngine-4.25/Engine/Source/Runtime/Engine/Private/ShaderCompiler/ShaderCompiler.cpp] [Line: 2397]
Failed to compile default material /Engine/EngineMaterials/WorldGridMaterial.WorldGridMaterial!
UE4Editor.exe has triggered a breakpoint.
I don’t understand what the platform PCD3D_SM5 is.
File for the world grid material is present at the location.
help please.
