For the people…
After countless Reddit posts, Activision forum support threads and web searching… I have finally found a solution for my Call of Duty Warzone crash. This will not fix every Call of Duty – Warzone issue but hopefully, it will allow you to at least load the game.
In my case my the game was crashing shortly after the intro logos appeared or as soon as this screen appeared. After researching quite extensively this issue is due to shader bug from months ago that still causes issues.
To fix this issue you will need to use Disk Cleanup in Windows. To access click Search and type Disk Cleanup.
After launching Disk Cleanup you will see the following screen:
DirectX Shader Cache should be your focus. Delete these files and restart your machine. On restart launch Warzone as normal. Hope this helps someone else :).
Update – As of 04/03/2020 this issue is still present. I find I need to repeat this process every 3-4days for the game to be playable. I found another thing to do which reduces crashes is to Enable – Skip Introduction Movie.
