Unable to play halo wars 2 on xbox one with disc

I am unable to start halo wars 2 on xbox one with disc

Have you tried completely powering off your console, including unplugging the power cable, then starting back up again? If that doesn’t work you could try reinstalling. May also be a problem with the disc itself so you could check for scratches - if it’s damaged you could contact your retailer or reach out to Xbox Support if it falls within their accepted criteria for returning: https://support.xbox.com/en-US/games/troubleshooting/disc-replacement-program
