In essence, the game’s UI system fails to draw frames properly, causing a fatal crash.

The error is generally caused by a breakdown in communication between the user's client and the game servers. The breakdown can be categorized into three main areas:

Navigate through the menus (Zombies or Multiplayer) for a minute, then back out to the main menu.

: Verify the integrity of game files via the Steam Library. 3. Check Steam Workshop Mods

If verification didn't work, the issue is likely in your profile data, not the game install.
