Teams on macOS taking up CPU and lagging

I'm not sure if it's because of Tahoe, but Teams will take up 65-90% of my CPU during calls, while only using 0.1% when not on a call.

This has been present in the dev betas, 26.0 and now 26.1. If I have other apps running, they or Teams can sometimes lag or glitch. Even with nothing else running, Teams can slow to a crawl.
