Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi,
You may try resetting your Microsoft Teams app if it helps:
Exit Microsoft Teams app (Check out if it appears in the
Windows toolbar and closes it).
Copy and paste the following path in File Explorer: %appdata%\Microsoft\Teams
Delete all contents in that folder (You may make a backup somewhere if you desire)
Restart Microsoft Teams.
Sign in and try again
Regards,
