Teams crashes on startup

After reinstalling my PC with Windows 10 20H2 I downloaded and installed Teams version

Now, each time I try to start Teams it crashes with Application Error ID 1000:

Hi @Marcel60  I wasn't able to find anything specific to Teams for this error but I found this video related to Windows 10: How to Fix Event 1000 Application Error on Windows 10 [Tutorial] - Bing video


Let us know if it helps.

Hi @ThereseSolimeno, thanks for the link. I tried both commands, but unfortunately Teams still crashes as before :( Are there any other ideas?
