Unity freeze while compiling scripts and running backend

I’m new to Unity and I started my first project several months ago and my project run on Unity 6. Everything still work great until a week ago, when Unity console said specified argument was out of the range of valid values. (parameter ‘length’). I have tried to reimport the project and after a few time, this happen: while I opening into my project, Unity freeze when it compiling scripts and running backend. Anyone have any suggest or solutions? This project is important and I’m so stressed out right now.

Hello, this happened to me too. I managed to solve it by downloading the project folder from iCloud directly into the computer. If it is your case too, try it. Goold Luck.
