Can you submit a bug report with a project that causes this issue?

3

I just solved it by myself. I had a newtonsoft json package in my project. this package was not shown in the package manager I had to remove the package from the manifest and package-lock manually

Solution__________

Hello here’s the solution if you change or move the project.
Remove Il2cppBuildCache folder (Project/Library/Il2cppBuildCache)
Mostly this issue occurs when we change the project location or moved the project to another location.
