Bug I can't login on the UnityHub Linux Ubuntu App

Hey I'm new to Linux so i'm quite lost. I installed the two latest versions of the UnityHub app for Ubuntu 20.04 successfully but i couldn't login. When I click on 'Sing In' i'm redirected to the browser to login, I do it and then a blank page appears where i'm asked to agree to 'Open xdg-open', when i click yes the browser continues blank and it isn't redirected back to the app logged in. The unity app keeps on the same login screen. I tried to login with Firefox and Chrome as the default browser unsuccessfully How can i solve this issue?
