Team macOS app not working
I've been using the Team macOS app for months now. Yesterday, out of a sudden it crashed and will not start up again. The app launches, but when it is trying to log in, this does not work (see screenshot).
I already tried to:
- restart mac
- clear some application data / caching things
- re-install teams app
It still is not working. I also attached the log file, maybe this helps.

Hi there .
The fact is it seems Teams got permission issue on macOS.
Maybe go on BigSur is a way .
I found this guide recently who reseolve this problem.

Today it decided to work after I connected using a VPN app supplied by our employer. Maybe switching to a different network or setting like this will help.

Same here, for weeks. Only web browser app works, and it has less features than desktop app.
