UE5 crashes when I select a nanite mesh for previewing a material. I tried it mith multiple meshes and I can use the preview if I disable nanite (but I dont want that ofcource).

Crash information:

Assertion failed: !bShaderMapComplete [File:D:/build/++UE5/Sync/Engine/Source/Runtime/Engine/Private/Materials/MaterialShared.cpp] [Line: 2542]
