I’m not using Apple products anymore, but this “privileged helper” issue showed up a couple of times here and, as far as I can see, it has to do with the MacOS start objects.
The link below had the same problem with the Library Manager and it looks like he solved it by modifying these start objects.
No don’t do that. Reinstalling the OS doesn’t help in about 99% of problems, it just takes a lot of time and, as you see, it gives you nothing.
