Hi, these shaders were made a long time ago (10+ years) before URP existed, as such the lit option can only work with the built-in render pipeline, since URP has its own lighting system that works differently in the shader code. I'm leaving them here since they can still be useful, and unlit versions should work in URP, but I don't maintain them anymore. For lit MatCap solutions working with URP, you can check my Toony Colors Pro 2 asset (though it is a paid package), which has MatCap support through its Shader Generator 2 tool. Thanks.
