I need some fortnite related help please

My son’s Xbox won’t let him (or me) play or uninstall Fortnite. Every other game and app works fine. I’ve cleared local saved data and have plenty room on the storage device. Whenever I click on the icon for it to play it does nothing for a couple of seconds then pops up with a ‘we are getting your game ready’ message followed by another error message after that saying that I can’t open the game. I’ve tried everything (I think). I’m beyond frustrated. Been fricking with this bullshite on and off ever since last week.

Has this ever happened to anyone? What the hell am I supposed to do? Any help would be appreciated, TIA


**I've tried to uninstall it as well. Whenever I click ‘uninstall’, it does absolutely nothing. Literally nothing. Doesn’t even flinch
