Call of duty not starting on 21286
In the release notes it is mentioned that some application such as Call of Duty Warzone and Call of Duty Blackops to not work with on Build 21286 https://blogs.windows.com/windows-insider/2021/01/06/announcing-windows-10-insider-preview-build-21286/ "
- We’re investigating an issue where Call of Duty: Modern Warfare and Call of Duty: Black Ops Cold War may not launch starting with this build. If you play these games, you may wish to pause updates until the issue is resolved."
Unfortunately I only saw that after I completed the update. Cod does not start in any way and a rollback to a previous Windows always fails.
Has anybody found a workaround? I guess the only solutions is to reinstall 
- The issue that could prevent Call of Duty: Modern Warfare and Call of Duty: Black Ops Cold War from launching has been fixed and is in the process of rolling out. Please update your game(s) to apply the fix.
- more fixed on today's build "We fixed an issue where certain games like State of Decay 2, or Assassin’s Creed, may hang or crash when launching." https://blogs.windows.com/windows-insider/2021/01/27/announcing-windows-10-insider-preview-build-21301/

Funny, Warzone had a pending update, so I installed it. But I had already installed the latest update from Cold War a few days ago. It turns out that after updating Warzone, the game opened without any problems. But Cold War still doesn't work. Should I reinstall it?
- they mentioned the update is in the process of rolling out, so maybe it will come soon ?
- Hmmmmmm, it didn't work for me, actually. I've just updated to the new release, and also tried to repair the game once again, but the bug persists. What should I do?
I got solution. Just installed latest NVIDIA Driver - 461.09
You can check download this driver from extended search page https://www.nvidia.com/Download/Find.aspx
I choose Standard version, you must delete NVIDIA Panel before install or Windows will rollback drivers to old 432 version.- Go to previous build . I thought it was a game bug but then I go into previous build and the game runs normal now 🙂 . This bluf not good 21286.
Okay, I just googled it and found out how to go back to a previous build.
I used this link to help me out. https://answers.microsoft.com/en-us/insider/forum/insider_wintp-insider_update-insiderplat_pc/insider-build-18947-information-and-how-to/3c371d12-e61b-4152-93e9-0975a2643208
I just installed the latest windows insider build update - Windows 10 Insider Preview 21286.1000 (rs_prerelease). I cannot play Modern Warfare now. I do see that the game launches and I see the process in the Task Manager but then it is suspended (sometimes, not all the time) or it just disappears from the list. Then the Blizzard launcher button changes from Launching... to Play Now.
I don't think I can roll back changes. I want a quick solution too.

Any improvements on this issue? I can't rollback to the previous version and I wanna play COD
I could also not Rollback to a previous version. As a workaround I installed Windows 20H2 on a seperate disk and can now dual boot 21292 or 20H2. In the 20H2 OS you can install Battle.net and point to the existing Call of Duty installation, in my case that is the same disk as 21292 is installed on. This way you do not have to re-download the 200GB game data.
