Problem while clicking on "Teams" button --> the "Files" page is opened instead

Hi,

I have a strange problem on MAC OS version of Teams. 

When I click on the "Teams" button ( to open the teams page ), the "Files" page is open. 

I have no way to open the "Teams" page.

On Window, everything works

I have uninstalled and reinstalled Teams, and that not solved my problem.

HELP !
