Stuck on menu screen Profile in use.

I’m literally stuck. I cant choose which game I would like to play. My screen says Profile In Use. This profile is already in use and cannot be selected. Please choose another profile. It has the option to press A for OK, but neither of my controllers will do anything.

This started after I started playing Halo 3.

I’ve reconnected the controllers multiples times. I’ve restarted the console multiple times. Other issues I have had are it saying there’s issues with my xbox live settings which I don’t use xbox live (or at least play online.)

After looking thru some other unrelated posts on here, holding the power button for 10 seconds solved the issue.
