Game will not open on Xbox one

Hey,

I just recently got back to playing games on Xbox one and bought halo wars 2. I was a big fan of the original and was looking forward to giving this one a try. However, I downloaded the game, which took forever since it was like 30G, and when I try to open it the title screen appears then it just sits there for a few seconds and returns me to the Xbox home screen. I wanted to see if there was any way to fix this or if I am just going to have to uninstall the game and reinstall? Trying to avoid this route since the download takes so long. Any information is appreciated. Thanks!
