Fix: Call of Duty Modern Warfare Warzone Dev Error 5523

Some gamers have complained that after downloading MW2, they encounter the dev error 5523, which sends them back to the dashboard.

The error occurs as you try to launch the game, and the game fails to load, thus affecting your overall gaming experience.

Why do I keep getting Dev error 5523 on Call of Duty?

• Minimum requirements not met – If your system does not meet the system requirements for Call of Duty, you may bump into the Warzone Dev error.
• Overlay turned on – Sometimes, you may encounter the error if the game overlay is turned on in the launcher.
• Corrupted graphics driver – Corrupted and missing display drivers are often the reason behind the dev error 5523.
• The game does not have permission – If the COD: Modern Warfare game does not have administrator permission, you may encounter the error.
• Pending Windows update – If you have not installed the pending Windows updates, that’s another reason you may encounter the dev error.
• A glitch with the game itself – It could be possible that there’s an issue within the game itself, and hence, you see the error. This turned out to be the case with Dev Error 841 in MW3.
