Teams not working on MacOS Big Sur

Hi all, 

I recently installer MacOS Big Sur in my Macbook Pro from scratch (not upgrading from previous installation). Once the system was working, I installed the Office 365 suite from App Store and MS Teams from microsoft.com (Teams does not exists in the App Store). All software is working properly EXCEPT Teams. After installation and launch, I keeps freezed in the "Loading Microsoft Teams" view.

I have uninstalled and reinstalled the package several times, restarted the machine, etc, but it still does not work.

Are there any procedures or fixed I should perform? Does Teams actually works on Big Sur?

Thanks.

    Dear all,

    I just noticed that only the initial startup of a fresh installed version 408872 does fail because it cannot successfully finish the initial setup process.

    Do the following:

    1. install a previous version of Microsoft Teams -I did it with version 333671-
    2. login to your Microsoft Teams account
    3. update to current version

    Now the current version 408872 will work for you on Big Sur 11.3.1

    Bye

    René

    Same issues - and none of the solutions worked. All Big Sur related. I had to ultimately do a roll back to Catalina.

    Another Mac Update that screwed up connectivity. Took hours to troubleshoot, then hours more to reinstall. 

    This should have been long tested and addressed prior to role out.

    My issues were back in January - seems like the issues are still not resolved.

    Did anyone come across this same issue? OSX Big Sur: I have tried deleting cache, the JSON method, no MS teams folders found. Gave full disk permits, accessibility permits, logged in on the web, it didn't even ask to use the desktop app when entering a meeting. I'm giving up...

    Seem to have same/similar problem. Except in my case the Teams first went into an endless startup loop. It closed immediately after opening and tried to restart endlessly. Removing the suggested folders in Library made things worse. Now Teams causes following crash EVERY time I try to open it

    This problem exists on a MacBook Air M1 (MacOS 11.4), while a year older MacBook (also MacOS 11.4) with Intel processor in unaffected. Not sure if the processor key, however, since we have another computer with M1 that doesn't appear to have the same issue.
