Engine doesn't load if SkinCache compiler is enabled

When SkinCache compiler is enabled engine stop loading a project at 39%… DX12 is enabled, Raytrace enabled… how can I fix it please?

Does it hang or crash? Are you using the official 4.25.1 version or the DQ version? If the second is true, it is due to a bug in the code of the custom made version, which can be fixed easily by adding a
#endif in line 262 in Shaders/Private/GPUSkinCacheComputeShader.usf

The problem could lie with your firewall, antivir prog or with VR projects generally (esp. with updating older projects to a newer version). Maybe a start of ue as admin could help as well. Other people reported that waiting some time helped, because big projects take much time to recalculate all shaders. (not only with updating old projects to a newer version but if you check or uncheck the recompute skincache box, force to recompute all tangents and restart ue too)

I’ve just double checked every single parameters. The problem it is not about SkinCache but when I activate RAYTRACE!!! (f…k)
Does raytrace works with every graphic card?
