Can you try the following:
Fully exit Microsoft Teams Client. (Right click on Teams icon from the icon tray and select "quit", or you can use task manager ;))
Next, run the following Powershell commands:
Remove-Item –path $env:APPDATA”\Microsoft\teams\blob_storage\*”
Remove-Item –path $env:APPDATA”\Microsoft\teams\Cache\*”
Remove-Item –path $env:APPDATA”\Microsoft\teams\databases\*”
Remove-Item –path $env:APPDATA”\Microsoft\teams\GPUcache\*”
Remove-Item –path $env:APPDATA”\Microsoft\teams\IndexedDB\*” -recurse
Remove-Item –path $env:APPDATA”\Microsoft\teams\Local Storage\*” -recurse
Remove-Item –path $env:APPDATA”\Microsoft\teams\tmp\*”
Restart Teams and see if problems are fixed.
Let me know!
