Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi Peppermint Squirrel,
Firstly, may I know if this is the first time to setup Teams app in this PC, if so, I suggest you compare the official article with the device situation to check if you need to upgrade the hardware: Hardware requirements for Microsoft Teams
If it worked before. I would like to know what device encountered this problem, Windows desktop, Mac, iPad, or mobile? And please login Teams on the web to check the results, so that we can know if your account is healthy.
Besides, if the problem is just existing in this PC, I suggest we can try these ways: update the Teams and OS to the latest version, re-install the Teams application; also please check if the problem persists after signing out and closing all applications which were integrated with Teams, such as Office, sometimes the problem is coming from other application.
We appreciate your time and cooperation, welcome back to us if there are any updates.
Regards,
Linda
