I have the same problem but to a much more extreme extent. If I answer a teams call or join a meeting with my bluetooth headphones connected it will not connect the mic and then crash the teams app. Even if I try to stay in the meeting just to listen in I will be repeatedly booted out of the meeting and have to restart the app each time. I use AKG Y400 heaphones and have been using them on teams on my previous laptop for over a year without problems. It was only after I upgraded to a new laptop that the problems started. I can only use wired headphones with teams. The headphones work fine for all other functions on the laptop. It is just teams that doesn't work.
Please fix this bug, bluetooth headphones are much more convenient for my work and I don't want to have to invest in a new set of outdated wired headphones just to use with a single app!
