Did you have an issue where the app wasn't recognised? I keep getting the message ' zsh: no such file or directory: TheLastStar_V1.0 '. If you have had that issue did you find a way to get around it?
Hmmmm no, I didn't have that problem.
How about deleting the app then redownload it?
When you redownload it, try to unpack the app then copy it to the Applications folder.
After that open a terminal where you will chdir to the Applications folder then do the chmod.
At least that's what worked on me.
If it helps, I'm using Mac OS Monterey.
