What is your Teams version now? Do you mean you could also meet the same problem in Teams web client?
In this case, we firstly recommend you try to clear your client cache file by following these steps:
Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray and select ‘Quit’. Or run Task Manager and fully kill the process.
Go to File Explorer, and type in %appdata%\Microsoft\teams.
Once in the directory, delete any file in the following folders:
%appdata%\Microsoft\teams\application cache\cache
%appdata%\Microsoft\teams\blob_storage
%appdata%\Microsoft\teams\Cache
%appdata%\Microsoft\teams\databases
%appdata%\Microsoft\teams\GPUcache
%appdata%\Microsoft\teams\IndexedDB
%appdata%\Microsoft\teams\Local Storage
%appdata%\Microsoft\teams\tmp
Meanwhile, if the above suggestion is not working, please contact with your Teams admin and try to disable and enable your account to see if it works.
