Loud static being detected by my microphone after 15 minutes

This happens randomly on calls with no apparent reason. I have to switch to another microphone (I have two monitors with built in webcam) and then switch back and it is fine. The noise is in the recording but I do not hear it but I can see the microphone level in the zoom call is bouncing around at the max level. Other callers hear wildly loud static (not as regular as white noise).

*Additionally, this does not happen in Microsoft Teams meetings.

I see there is a long history of this happening in Zoom calls. Meetings are the core function of my work but the pro plan does not include support. Please, any ideas are welcome!
