The shaders don't work when the option to override scene light and use a camera attached light is used (the light bulb symbol near Draw mode and 2D view toggle).
The compiler was complaining about _DebugViewMaterial not being defined, so I swapped the code with what seems to be a new version of the ShaderPassForward.hlsl and it cleared the error, but the materials are still pink.
I can make a PR if you want with the change, but I don't know if more things changed. There are no errors but some warnings appear.
