I see a MacbookPro running OSX Catalina 10.15 connect to your account on Dec 28. Did this problem start when you upgraded the OS from v10.11.6?
If so this may be related to the the changed in folder permissions that Apple implemented in Catalina. For some users, denying folder permissions resulsts in the app not starting at all. For others, it may create flaky app performance.
Please see this previous thread and see if manually enabling folder permissions clears it up?
