Microphone not working mid call

I use teams with my bluetooth headset. But all of a sudden few weeks ago my problem starts.

Micrphone is unmuted, but nobody can hear me. When i go to audio settings switch to notebook mic and back to headset, it works. Then i mute mic and again unmute and again nobody can hear me.

I didnt change anything. I dont know if its so hard for M$ engineers to make simple IM app where the basics work without issue.

Really hate this app and somebody from M$ should be fired for this piece of sh*t.
