Sooo, Teams is working with Beta 5 no issues. Outlook on the other hand has stopped working completely. :-/

So far, no issues with Teams after using on beta 5. Fingers crossed.

installing beta 5. will report back if the issue improves with the new version.

I just noticed that if I run WiFi and a Wired Ethernet connection, I can get the app to perform normally. Something you might want to give a try
