During normal start up it will go to the green xbox screen with loading dots on the bottom then it will display a black screen. If the black screen is what your talking about give it a minute for the xbox logo to pop up. The console is loading the dashboard
when you see that screen.

I go on the game but its a black screen or a continuous loading screen.

I have a similar issue. For me when the game launches it either stays at a black screen or gets to a loading screen but never loads

This exact problem happened to me. I just updated and boom just black screen instead of home screen. I click report a problem and it goes to open the app then black screen. I put in a disk and loads up the game screen and then black screen.
