Non-Multipass fails to render in Unity 6

[fenhelix]

Although multi pass seems to be working flawlessly in Unity 6 I'm having issues getting PhysicalHair, Performant, HighFidelity, and BakedLighting to render anything.

Looking inside the frame debugger it appears as if the material isn't assigned even though that is not the case. The shader doesn't occur in any part of the render pass. Any ideas on why this may be?
