Update - Warzone is now working. It must be due to Windows update or other such update. As you can see I am still running the same motherboard, CPU and Windows 10 version. Thank you all for your help and comments.
And from my Settings:
Edition Windows 10 Home
Version 22H2
Installed on 19/09/2020
OS build 19045.2311
Experience Windows Feature Experience Pack 120.2212.4190.0
It is saying I am on windows 8 every time I try to load up Warzone even though my settings say I am fully updated on which I assume I am on Windows 10.
I am failing to run Call of Duty Modern Warfare Warzone 2.0.
Every time it asks me for an update and when I update it, it fails saying 'something broke'. I have no issue with storage and have a wired connection.
