I have to reload HALO 5 when I change games.

I may be done with Halo 5. If I change games, say to MCC, I have to uninstall then reinstall Halo 5 in order to play again. My game disc is fine. System asks if I own the game and will not let me play. Had the game for years with no trouble at all. Tried hard reset, called Microsoft support, nothing helps. Anyone else have this issue? Any fix or workaround?

Maybe it’s your system if your 100% sure the disc has no problem.

Odd thing is it reads the disk, just says I don’t own the game.
