Good day, I was working on a Game in Unity 2019.2.1f1. Then I upgraded my Unity to 2019.3.6f1. When I was opening & upgrading my game to the new Unity version. I got a warning popup saying: Unity Package Manager Error. An error occurred while resolving packages: One or more packages could not be added to local file system. com/unity.ads:EACCESS: permission denied, unlink /users/myname/mygame/Library/PackageCachefirstname.lastname@example.org/CHANGELOG.md' The popup gives me 3 options: 'Quit' 'Continue' 'Retry' When I 'Retry' the popup keeps showing up again and again. When I 'Continue' Unity opens but then my Mac crashes and shuts down. I have an iMac 2016 Model with macOS Mojave 10.14.6. Can someone please help me? I'm stuck and I can't do anything. I even went back to my previous Unity version but I keep getting the popup.
