For the most of the crashes i got a FIX.
Problem 1:
COD-W is using CPU and only 10% GPU
Go to your PC>Documents> Call of Duty > config
in there you will search for something like
setcl -“Some Random Numbers” “Nvidia Gefore RTX 2060” (thats my GPU make sure you got it like this for your GPU!!!)
Safe settings and put it to read only ! right click on config > properties > read only
Problem 2:
If your Game Crashes or Freezes in the Launch go back with your Nvidia Graphic Drivers! Select your GPU and choose the Driver from January, after investigating the files theres is a bug in the newer Versions of the Nvidia Graphics Drivers which cause COD-W to Crash/Freeze or even loosing Singal to the Screen!
Those Fixes worked for me so it may help You.
Just wanted to share those
