Teams Crashes with Bluetooth answered calls

luvsql I have a similar issue. I cannot use the Teams app on W10 at all as it completely knocks out BT devices (Sony WH-1000MX M3 headphones and MS Surface BT Ergonomic keyboard) or the app just hangs and won't go beyond the startup. I have to use the web app and then when someone shares their screen (I'm not 100% sure this is the trigger) it nerfs my keyboard (the wired one I've had to plug in to get round this works fine) until I close the browser to end the call. When I try and type, the whole system (yes - the whole 32GB, i7 PC) locks up for ~5 seconds like some kind of kernel panic and then comes back to life again.

Zoom, Webex, Bluejeans are all fine on exactly the same setup so this is definitely an issue with the MS BT stack or, more likely, what they are trying to do with it in the background.

Quick tip for anyone else: if your BT keyboard won't connect at all after it drops out, just jump into Flight mode an out again and it will reconnect.
