Happens randomly after a short period of time when the game is autosaving or I'm doing it manually. Sometimes it's showing message "copy_file(p1, p2, options): invalid arguments: operation not permitted" before the crash. Please help because the game is unplayable for me, thanks.

Does it happen on every save process? Does it happen on new created games as well? Disable your antivirus solution and test if it still happens then.
