Yeah as suggested you may want to do a power cylce/refresh of the console, ie. clearing the cache
This operation has solved a problem where, when starting a game on the Xbox One, the system would show just the initial picture page of the game, and then return to the Home screen without starting the game. This particular problem did not affect Apps on the Xbox One, but only games (downloaded or disc-based). Once this operation was performed, the Xbox One was restored to full functionality.
Also bare in mind that the servers are having some issues right now which can be seen here
