Call of duty MW3 crash error 0xc0000005 (n) in zombies only, this only happens in the zombies mode only xbox gamepass version
The fix that worked for me was to uninstall the game and go to your settings and change the region to United States, then restart your pc and redownload the game, this works for pc and xbox as for ps5 you cant change region of your account so i dont know a fix for the game on it.
