Outlook crashing with iCloud for Windows - cannot use sync calendar and contacts

Windows 11 Home

Microsoft 365 16.0.19127.20154

iCloud 15.4.210

Per another thread, tried uninstalling iCloud to replace with an old 7.20.x version. Same issue. It syncs data so I can see a snapshot but the add-in will not run. Done repairs on Office, iCloud, etc. I've seen other threads that are closed with no resolution. This an insane thing not to work - I've had this setup for years and years.
