PCloud no longer works on Macs with Ventura or Sonoma - any fix?

PCloud was a folder on my Mac for years. Simply loaded and opened automatically. Update to Ventura - it cranses - have to log in each time - and set permissions. Sonoma killed it entirely - simply get an outdated dialog in an error message telling me to go into settings - to a place now changed in name - to set permissions - the permissions are already granted. After uninstalls and reinstalls, including work in recovery mode (and 75 minutes with Apple Advisors) it still does not work. Any thoughts? The Apple people - after all that time - are saying the App provided by Pcloud is faulty with the newer versions of the Mac OS. Any other ideas?
