Teams stopped working, language pack causing trouble. (?)
Norwegian is system language. After installing 22000.168 Teams app was a mix of Norwegian and English. It did not help setting Norwegian as language within the app. I cannot be 100% sure, but Teams froze the moment I set app language to Norwegian. I tried to reset Teams App, did not help. When I tried to uninstall, nothing happened. Was able to uninstall from safe mode. Downloaded Teams, and it is working, it is in Norwegian. Problem solved. I posted this in case someone else should run into a similar scenario with mixed languages, and / or a freeze.
