Mac Teams Client - Main Teams window stops displaying after a few days

RichBaldry 2 years later and this remains an issue - its very annoying. I also notice, that when you restart it often takes a while to get Teams running up to the point where you can actually join a meeting. I wonder if bluetooth headsets might be a contributing factor (do they cause the disappearing window - haven't been in a position to run without a headset for a few days to try) - as when I restart Teams, trying to connect audio is then an issue and often I will get an extended "joining" message as I desperately try to get into the meeting I am now late for as the window was gone.
