You might have to uninstall the game and re install it,it should fix your issue

If you play siege on a disk, there might be a problem with your disk, or you may just have to re-download the game to keep it up to date and make sure its running how it should.

Hello,

I've experienced this issue a few times with different games and I've found that pressing the Xbox Guide Button, pressing the menu button when you've highlighted R6S, and closing the game that way. You should be able from that point to restart the game with
no issues.

Hard reboot should do the trick. Hold the Xbox logo on the system until its completely shut down and then restart with your Xbox controller.

May have to uninstall and reinstall the game
