I got the same issue too! My system is macOS Monterey ver 12.7.2. However, instead of getting the msg you got, mine just showed "the application cannot be opened -50" when I press ESC. Tried reinstalling, updating the system, changing the privacy and security settings and importing the files by hand ( that's all I could think of as a computer noob, sry ) and none of them worked, now I can't do anything on the app. :c
