Can you please perform the resolution steps below:
1. Sign out from Teams
2. Clear the Teams credential through:
Search for Credential Manager > Windows Credential > Delete ALL Teams cache credential
3. Delete the Teams cache through below and delete everything inside
%appdata%\Microsoft\teams

Kindly confirm if this helps or if you still need further assistance.
This method works similarly on a Mac by deleting the following directory; ~/Library/Application Support/Microsoft/Teams.
