Not able to load Warzone on Cold War disc (Xbox one)

Hello there @J. Davies, I hope everything is going well!
Thank you for reaching Microsoft Xbox Forum support. I want you not to worry about the situation because I am here to help you out! I believe your console might need either a network reset or just a system refresh. I would like you to go through the following steps to clear the Mac address and then perform a quick power cycle on your console:

Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear it and the console should restart. It would definitely help if you could restart the internet router while the console is restarting.

After going through the troubleshooting steps mentioned, I invite you to perform a quick power cycle by turning off the console and then unplugging all the cables. After 2 to 3 minutes, re-plug them back again, then restart your console.

The next step would be to check your NAT type. I would like you to check your NAT type if open because that could sometimes interfere. to check for the NAT type you can follow the steps below:

Settings > Network Settings > NAT type => It should be open.

If the NAT type is not open, you will need to open some ports with your internet provider. These ports must be open for Xbox Live to work: Port 88 (UDP) Port 3074 (UDP and TCP) Port 53 (UDP and TCP) Port 80 (TCP) Port 500 (UDP) Port 3544 (UDP) Port 4500 (UDP).

If needed or if it’s dirty or scratched, wipe the disc with a soft, clean, slightly damp cloth. Hold the disc by the edges without touching the top or bottom faces, then re-insert it and try launching again

Another thing you should troubleshoot is your persistent storage by selecting Profile & system > Settings > Devices & connections, and then selecting either Blu-ray and then select Persistent storage to clear it.

In case the issue still persists after the previous steps have been performed here is the official link to all the network troubleshooting steps that can help sort this out for you.

The link: Troubleshoot your Xbox One network connection | Xbox Support

In case the issue still persists, the next step would be to perform a reset on the console. To do so you will need to follow the steps below to perform a reset on the Xbox :

Settings > System > Console Info > Reset This Xbox > Reset and Keep my Games and Apps.

Note =>The "Reset and Keep my Games and Apps" option will not cause losing your games, but please be aware that you need to be completely aware of the email address as well as the password of your account before going for it because it will require you to sign in to the account.I wish you a lovely day, and I hope this helps you out! All the best!

Kind Regards

Stay safe, and happy gaming!

? There is a warzone for cold war right?

Do you understand my problem? Please help..

I uninstalled modern warfare.

,launch cold war, went to warzone and it still took me to the modern warfare warzone,..

I thought there was a new warzone map for cold war and it had zombies...??

I got the same problem right now. Trying out Microsoft's solution. Will update.

I had warzone on Xbox series x. Deleted it and bought cold war on disc. Can't install anything. So I'm doing the advice from Microsoft but maybe warzone interferes with cold war because it was a "freestanding" part of the game and now i somehow got both?

A few examples would be, CarX, Rainbow Six, Warzone, Cold War.

I turned the 4k off on my console and that fixed the warzone issue. Just don’t understand why Cold War works fine with the 4k on but warzone was a constant crash. Thanks for the work around solution!
