Verification Failed Action cannot be completed.

This started after a Windows 11 Pro Microsoft Update this morning. I've logged out and back in and rebooted. I've also tested a wrong password and get a different error. All else sees the 'net just fine. iCloud installed via Microsoft Store. Microsoft Store offers no updates to it. All I can do is Cancel and then a few minutes later the Enter your password to continue using iCloud dialog pops up again just like a Jack Russel Terrier. Enter password. Verification Failed. Rinse and repeat.

Anybody else seeing this today? Any thoughts for next steps?
