Game won't start

I recently installed Halo 5 on a new Xbox, and when I try to start it, it won’t load. I select it, the screen with Locke and the Chief shows up, but it then takes me back to the Xbox dashboard without saying anything. I have the full game installed, 97.4 GB. I’ve had this problem for a few days now, and I’ve tried restarting my Xbox, and it’s the digital version.

Try to launch it from game hub.

Might be worth trying to reinstall and see if that helps
