MuseHub is "unable to connect to Helper". Help!

Hiya, I'm getting this odd error. Searching the forums, I've tired everything posts with similar issues recommend doing. I've rebooted my Mac, reinstalled MuseHub multiple times, given MuseHub full disk access, deleted the com.muse.museservice file from the PrivilegedHelperTools folder, to no avail.

If anyone here knows how to fix this, I'd appreciate some help very much.
Thanks.
