The Dev error 5433 can be spotted in Call of Duty Modern Warfare 3 or Warzone. The effects include a screen freeze and the inability to play in multiplayer mode.

The Dev error 5433 is mostly a memory error but it can also be a compatibility issue. Some integrated graphics cards are limited and cannot accommodate certain texture sizes or memory allocations hence why your screen freezes or the game crashes.
