What is Dev Error 5573 in Warzone?

Dev Error 5573 is an error code caused by corrupted game files. The error is highly prevalent in Playstation and PC versions of the game. 

It causes the game to crash and gives you a message that says, “Dev Error-5573.” In most cases, the game crashes after a few seconds.

Additionally, the problem persists throughout the PS5 version of the game. 

However, it is relatively simple to explain and fix. Dev error 5573 prevents you from playing matches smoothly in the game. According to reports, the error disrupts online matches. 


After which, the player is completely thrown out of the game and crashes. 

Corrupted game files or data mainly cause the game’s Fatal errors. As a result, the game is essentially unplayable in most cases. 

Because of this, it is quite similar to other game-breaking issues in the game, such as the Error Code Diver and the Error Code Vivacious.

Infinity Ward has continually addressed this kind of major issue with the game. However, the game has significantly improved since the patches and updates were installed. 


Call of Duty Warzone is a game with many assets and other dimensions; it is rather easy to have so many problematic development errors.

What Causes Warzone Dev Error 5573?

Upon investigating this particular issue thoroughly, it turns out that there are several reasons why this error code might be happening. 

The following are some possible reasons which could be causing Dev Error 5573:

Cold War items are part of your loadout:- Some Cold War items seem to facilitate this error code’s appearance. PELLINGTON + FFAR is the most notorious combination that causes this error code. To avoid the error, you’ll need to remove all Cold War-related items from your Call of Duty Warzone layout.


Cold War Operator is being used:- Keep in mind that Cold War items aren’t the only ones that cause the 5573 developer error to appear. 

Many users who have dealt with this problem have reported that Cold War operators can also cause this error. 

You can circumvent this issue by changing your active operator to a native Warzone one (at least until it’s fully fixed).

Insufficient bandwidth:- If you’re constantly experiencing this issue while playing a game, you should also consider that you might be experiencing a bandwidth issue (especially if you’re using a wireless network). 


To resolve this issue, you may need to test your Wi-Fi signal strength and, if necessary, take steps to improve your effective bandwidth.

Automated Voice profanity ban:- Some users have experienced this error when they’ve been hit by an automated voice profanity ban while playing the game with voice chat enabled. 

You should open a support ticket if you tend to swear when playing so we can check if a ban is causing your Dev error.

Game file inconsistency:- If none of the methods above have worked for you, you should try repairing or reinstalling the game to ensure that the game is not corrupted. 


This procedure will differ according to the platform you are experiencing the issue on.
