Series X - Crashes After Cold War Update

Yes it happened many times lastnight.

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."

Call of duty Black ops Cold war for Xbox one and Xbox series X.

Does the ultimate cold war version not work on the Xbox one?? Is it only for the series X?
