Cold War x/s disc version crashing and lagging badly every game I play

I accidentally purchased Cold War standard edition on my Series X. The standard version is barely playable because it always crashes the console. I tried to get a refund for the game, but it was 16 days and not 14 days after digital purchase. I would like
to get the cross-gen version of Cold War, so that I can play without it always crashing. So far Xbox support has denied my request based on the 14 day rule. I think they could make an exception.

From what I can tell, to access the Series X version of the game, you need the Cross-Gen bundle...once you buy that, you should then be able to download and install the Series X version. Without the cross-gen bundle it will, presumably, just install the XB1 version

From the Store page:

"For digital owners of the Call of Duty®: Black Ops Cold War Standard Edition, this upgrade will unlock the Call of Duty®: Black Ops Cold War Cross-Gen Bundle, giving access to the Xbox Series X|S version of the game. After upgrade purchase, search in the Xbox store for the Call of Duty®: Black Ops Cold War - Cross-Gen Bundle to install the Xbox Series X|S version of the game."

Can you provide more information? Which console are you using? Which version of Cold War? Have you tried logging out of your xbox and then re-log in, this will sometimes fix license issues.

There is a known issue if you are trying to play the $60 version on a Series S|X. Playing that X1 version results in hard crashes. You'll need to upgrade ($10) to the x-gen version if you have not. It wasn't very upfront.. a lot of us, myself included, ran
into this.

All else fails, uninstall the game and go to your game library, and download it again from there, make sure it says you own it before downloading. The Series X|S version is 130GB.

Yes. Xbox One games will be backwards compatible with the Series S/X. There are also games like Valhalla and Cold War that support Smart Delivery. With Smart Delivery, you can buy the games now on the One and you'll be able to download the Series S/X version
for free.

I crash on 2k21 next gen version. Some on cold war. Sometimes even on the dashboard.
