I thing it has something to do with old config or game files. The following fixed it for me.
Steps:
- Go to My Documents(C:\Users\{User}\Documents\) and remove the folder named "Call Of Duty Black Ops Cold War".
- Open the blizzard launcher -> Press the options(Next to the play button) -> Show in Explorer -> Remove the folder named "Call of Duty Black Ops Cold War".
- Uninstall the game using the blizzard launcher, Press the options(Next to the play button) -> Uninstall.
- Download the game again.
- ???
- Profit!
There is a change, it will work if you only do step one, if not repeat step one after you close the game or it crashes and follow the rest of the steps as well.
