Thank you for your reports. We released client and service updates this week, that address many MacOS-specific performance issues. We are also aware of recent performance issues with Microsoft Teams meetings, especially on laptops and when using external monitors.
The team is working to resolve these issues. In the meantime, please find troubleshooting information here: https://docs.microsoft.com/microsoftteams/troubleshoot/known-issues/teams-slow-video-meetings-laptops-4k.

Hard to find things that I haven't tried or symptoms not reported by others, but a possible triggers seems to be print screens of Teams Screen... sometimes I loose control of my 16" Mac for more than 10 seconds with a frozen screen, audio remains ok. External monitor makes it worse.
