At my previous job, MS Teams worked perfectly. It was used for everything, and it was great on my work laptop. Yesterday I had a Teams meeting with a teacher from my son's school, and Teams outright refused to work on my private laptop, with no indication why. The app when opened just hung on a white screen (even after reinstalling), and in the browser everything worked, except the camera. (The camera works fine in Discord or Google Meet.) I have no idea what the problem is here. It works perfectly fine in one situation, and not at all in the other. Both Windows machines.
