Campaign Freezing

I was playing Halo 5: Guardians’ Reunion mission solo when I had to briefly pause the game. Upon going back into the game, the game began temporarily freezing at random intervals. I recorded this happening, but it continued further into the mission before I ultimately made the decision to quit the game out of fear of losing progress to a crash. There was no obvious cause such as the game loading anything, and this has never happened before on either this mission or any other game I own. This all happened a couple of minutes before I made this post.

I’m playing on an Xbox One S (should that information matter.)
