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.

    Graham, I have the latest download, 97.7MB and it just hangs on the loading screen, Big Sur 11.1. Won't even open. How is it working for you?

    I had same issue with Team hanging on loading screen.

    I quit Teams.

    I deleted this folder

    ~/Library/Application Support/Microsoft/Teams

    Then started teams and signed on with a different account.

    That failed with a message and then I tried to sign in with the original account and it worked.

    Hey! I navigated to this same Library folder and there are none of those files there already. Very weird huh?

    Hi Nik,

    Thank you very much! The first solution didn't work but the second one yes!

    The most important thing is to log in with an account. If you only have a business account, create a personal one and log in with that one.

    Afterwards, when you see the dashboard you can try and log in with your desired account.

    (deleting the /Teams folder from Application Support / Microsoft / Teams in-between tries is also a must)

    It seems like the initial login process is blocked somehow when you try to do it with no account added or before the app dashboard is shown. 

    Pretty obvious bug if you are trying to use a business account (which most of us are...)
