Hello
My Teams suddenly stop working since Tuesday and show below error message. I tired to re-install it but did not solve the issues. I also deleted the Teams folder, keychain, but did not work also. The only solution is to install an old version of teams but then it will automaticity update it and then will stop working again. My Mac is in the latest version. Any ideas?

Hey, I'm having the exact same issue. I downloaded an older dmg and installed it and it worked for a while, but for some reason it's reverting back to this screen, even after turning auto updates off. Did you find a fix?
Dear edmund3,
Thank you for posting in Microsoft Community. We’re happy to help you.
I understand that you’ve tried clearing caches and reinstallation to no avail. I recommend you check updates for Mac, power off and start Mac device, then test it again. Please also sign in Teams Web App or Teams mobile app as a workaround.
