Can't log in to game

I get stuck at infinite login screen. Playing on Xbox One S. Game worked fine two days ago

I can sign in as a guest but not as me! WTF??

I don’t understand your issue.
Can you post a screenshot?

You don’t understand? When i try to log in I’m sick on the black loading screen forever. I have to do hard reboot of Xbox One and then start game again to log in my account. Otherwise at the screen that says press A to log in or X to log in as guest I can press X and play when I can’t log in my account

I don’t own a Xbox, so I don’t know what you’re talking about. On playstation you don’t need to login to the game. You start it and then you directly land in the main menu.
