Microsoft Teams file sharing doesn't work

Good evening,

I registered  a new Microsoft Teams Free account and I've the need to share files through the OneDrive file sharing section but when I click on the section the page states "An error occurred, try or refresh the page".

I've tried to delete and re-create the team itself ( teams' name is just letters "videocorso").

I've found another solution on the internet related to Sharepoint synchronization but I don't have Sharepoint in a free version of Teams.

I've attached a screenshot about the issue.

None of the solutions stated above did the trick. Is there any suggestion? 

Thanks for your support.
