Game isn’t loading at all!

Hey! So for the last three days my game has not been able to let me play it. It loads up fine but when I am at the main screen and click on resume it loads but then stops at about 80% and doesn’t load anymore. Last night I wanted to see how long it would still “load” and I had to log off after waiting for 2 hours. I even uninstalled the game thinking that would work. When I installed the game again the same thing is happening. I just want to play my favorite game and for days now I can load in. (Playing on Xbox)
