The games on xbox one

Crashes watch dogs 2 on xbox one s
The problem is that I bought a CD BU. The game runs, all the rules, but can hang at any time, e.g. 20 minutes or an hour, but it hangs when not doing missions. After the hang-up crashes to home screen. Tried to play FIFA on the disk (the new disk) all the rules, a half hour of the game and everything is fine.
The question is why and for what reason it happens, it's in the console or is it still in drive??
I would be very grateful, thank you all Araneae)
