MacOS Monterey Beta 4 and Microsoft Teams

I had the same issue on Beta 4 on M1 Mac mini. But with beta 5 Teams and Outlook both working for me

Still having issue on M1 MacBook Pro. Outlook is sweet, Teams is dead. Error code - 2:-1012

Beta 5.

never mind... ☹️ Issue has reappeared in Beta 5

Beta 5 got Teams working again for me.

Teams crashing on Monterey beta 21A5304g. I tried deleting Teams using App Cleaner and reinstalling. No use. No use after reboot either.

I got my teams running again after some time. In my experience (with Beta 6), the credentials stored in Teams are corrupt. When I logged in with my personal account (not business account) I was able to use Teams.

Unfortunately it is not possible to remove the credentials by clearing the cache. In my case, I uninstalled Office, cleared the cache, removed entries in the keychain, restarted the Mac, and then reinstalled the entire Office suite.

My credentials were still saved, but it asked me for a password again. After entering the password, I was able to log in again.

I know that these tips are of limited help. But after about 3 hours of research I got it running :-)

BTW: MBP 13" (Apple Silicon, M1)

Using 12.0.1 (21A558) (RC), Teams will not work if I receive an incoming video stream.

Audio based calls work fine, however, as soon as someone joins a Teams session and sends video, Teams will immediately crash. In earlier Monterey Betas it would crash maybe half of the time, but, a restart of Teams would likely let it work. However, with later betas, and with the RC, I am completely unable to run Teams on macOS with an incoming video.

Tried running from the command line to get useful information, nothing, but, the logs that Teams generates itself show the crashes and it's 100% repeatable.

At the moment, the only way I can use Teams is if I run it in a Linux or Windows virtual machine.
