Teams crashes on startup

[Marcel60]

After reinstalling my PC with Windows 10 20H2 I downloaded and installed Teams version 1.4.0.2879.

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

Does anybody know the reason or how to solve that issue?

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?

Hi @Marcel60   Unless anyone else in the community has a suggestion, I think you should go to answers.microsoft.com for personalized tech support.

I had the same problem on my work-computer. 

The problem was the fact that my folder "Application data" was located to our server. 

I made a copy of the appdata map from the server to my local computer and redirected the appdata folder to my local computer instead of our server.

That fixed the problem. (and for other troubled programs too)
