Hi Chris,
There was an issue identical to this picked up in late 2020, it was linked to a MacOS upgrade which locked down the security tighter. There's a fix for it, but the permissions need to be applied at the Mac end (I can't do anything in the software). There's a thread listing the error, explaining the issue and finally providing the fix:
/g/duncanampspsud/topic/77707176#msg20If you get an opportunity to try, please feed back and let me know if that fixes things for you.
Regards,
Duncan
