Warzone Disc read error?

Wanted to play warzone on xbox again after a while, but I get an error message with 'Disc read error', but I don't have a disc because I downloaded it from the store. And then it apparently always crashes but then immediately starts again by itself.

What could that be?

Can't say exactly what the problem is, but I've seen other people on the internet have the same problem. Just google the mistake. Maybe you can find something. Otherwise contact the support
