I can't join a club in xbox.com

I have a club invite in my Xbox profile, but when I click "Accept Invitation" it returns a 403 status (forbidden).

I can't upload an image here, because uploading is failling, but I'm sending a link:

I would like to add that since the deprecation of Xbox Console Companion, I can't find any clubs in Xbox PC App. There's no such a thing in the new Xbox PC App.



So the only way to find clubs is in Xbox.com but I can't accept my invitation, neither I can decline invitations.



On both of my Pcs I have the same problem. Win10/Win11. Internet connection is ok though.



Thank You

:)
