big sur – Syncing with Google

I am a new mac user who owns Macbook Air M1 with macOS 11.5.2.
I have a problem when I am trying to add a Google account in my internet accounts to sync (not mail) with Authorization Failed Error once I click on Open Browser.

I tried changing my default browser to Google Chrome but no clue.

Note: my apple ID is created using a Gmail account

What can I do? I tried searching for solutions but nothing helped me and I need a solution urgently.
