So strange - I reset my password and then also got stuck in a loop. The weird thing is that you can see all the latest updates behind the sign-in dialog!
The fix for me, was to wait until it was showing the error message, then right click the tray icon and sign-out. Then I was able to sign-in and access Teams again.
Every other O365 app was able to handle it without a loop though!
