Haven't played Call of Duty Warzone for a few months.
So I updated the game yesterday, started it, got to a loading screen, crashed to desktop. Every time.
Ok, rechecked game files. CTD.
Checked and reinstalled the latest GPU driver. CTD.
Uninstalled and reinstalled game. CTD
Uninstalled, removed all files from drive and reinstalled game. CTD.
Uninstalled, removed all files from drive again, cleared and reset all settings, and reinstalled game. CTD.
Uninstalled, removed all files from drive again, cleared and reset all settings,
went medieval on all relevant hidden files under AppData, and reinstalled game. CTD.
Wait a minute. "Unload Windowblinds". Bam, game works fine.
Exclude game EXE. Works every time now.
But still took a few hours to figure that out.
