Mac Authentication Error Starting 8/7/2024

UPDATE: I was forced to clear my OS and start over. Recovering from Time Machine brought over too many support files even when being picky. I have re-installed Teams from an old installer in a previous Time Machine entry and I am able to log in. This may not last though. This was obviously extreme and I hope you all do not have to do the same.

Teams for Mac recently updated and totally broke the functionality of Teams. I do not have connectivity to my work account at all. I had deleted all Teams file on 8/8 and reinstalled the Teams Classic which worked well. I came back to my computer later that afternoon and the new Teams had reinstalled itself. I went out of office until today and I have a repear error of "We couldn't authenticate you. This could be due to a device or network problem, or Teams could be experiencing a technical issue."

This is a Teams technical issue due to the repetitive error and my ability to sign in via iOS and web with the same credtentials on the same network, and in once case, the same machine.

Teams version 24193.1708.3043.1759

Client version 50/24071128823

    I have also a User with that issue.

    We made a whole reinstall of Office.

    Then the issue was still persisting.

    We Used Offie-Reset: https://office-reset.com

    Teams and OneNote was working again.

    OneDrive was still not working, so we used the /Applications/OneDrive.app/Contents/Resources/ResetOneDriveAppStandalone.command

    Then it worked fine for one day and stoped working again (Teams & OneDrive).

    Then he made the OneDrive reset again: /Applications/OneDrive.app/Contents/Resources/ResetOneDriveAppStandalone.command

    Teams and OneDrive worked again but stopped this morning again.

    Device Informations:
    MacBook Pro 14-Inch M3

    Model Number: Z1C80009LD/A
    macOS: 14.6.1

    Teams Version: 24180.210.3001.6635 (24180.210.3001.6635)
    OneDrive Version: 24.156.0804.0002

    This is just a temporary fix since the issue will usually return after a day or 2, sometimes sooner. This seems to be a bug and Microsoft needs to provide a fix.

    I did a clean install and found the installer for Teams Classic. So far so good. It goes dark in 28 days though.

    Edit: Clean install of the OS.
