I can't open my Unity Project

I have installed the Unity 2020.3.24f1 version. Every time I open a project I get an error message saying that compilation errors have occurred and that I should go into safe mode to fix the errors. When I try to open Unity 2019.4.13f1 it does not happen. Is there any way I can fix this?


Try installing the Unity Test Framework in Unitys package manager.
