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.

    After multiple attempts, and using Teams on my iPad Pro, I was FINALLY able to get Teams to load on my M1 MacBook Air.    I downloaded and installed the software.  Then I did the following and it worked.   All you have to do is click on an event in your calendar and then it will set up.   THANK YOU!!!!

    Step1 - Open any previous our upcoming TEAMS meeting invite from your calendar or emails.

    Step 2 - The pop-up will prompt you to open the TEAMS application - allow.

    Step 3 - It will prompt you to sign-in if you are the meeting organiser

    Step 4 - Sign-in with your login credentials 

    Step 5 - The pop-up will prompt for your permission to allow Camera and Microphone access.

    Step 6 - You are all set."

    Hi Justin,

    Try by removing the old installation and re-installing the Teams alongwith Rosetta and then follow the below steps:

    "There is definitely a programming flaw in MS Teams application for Big Sur update however you may bypass this issue by simply following the above mentioned steps which is :

    Step1 - Open any previous our upcoming TEAMS meeting invite from your calendar or emails.

    Step 2 - The pop-up will prompt you to open the TEAMS application - allow.

    Step 3 - It will prompt you to sign-in if you are the meeting organiser

    Step 4 - Sign-in with your login credentials 

    Step 5 - The pop-up will prompt for your permission to allow Camera and Microphone access.

    Step 6 - You are all set."

    Happy Teaming!

    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.

    HERO!!! thi fixed my issue of the hanging log on screen! Comon Microsoft, are you serious...? stuck on a log in screen and when login in as guest or with other O365 account of different organizations makes teams loading... Afterwards sign out and without any changes to my current real organization I can log in.... how is that even possible...

    I found a work around if anyone needs it. Instead of running the Teams app, run the web version of Teams until Microsoft updates the app. Allows all features.
