Exception: Unity.IL2CPP.Building.BuilderFailedException: Build failed with 0 successful nodes and 0 failed ones
Error: Internal build system error. Backend exited with code 2.

I searched but couldn't find the solution or known issues.
Does anyone know how to fix this?
My environment
macOS Monterey 12.5
Unity Editor 2021.3.10f1 Silicon
Well... I found the solution and will leave it here for someone who faces the same issue in the future.
You just need to remove Il2cppBuildCache folder under Library.(ref)
I think this issue was happening because I moved the project to another folder.
