How to fix
Call of Duty: Warzone DEV ERROR 5573
on Windows

Hi. Whenever I play  Call of Duty Warzone 2, I sometimes get thrown out of the server, and DEV ERROR 5573 pops up. Please suggest any solutions because it is really annoying - I can't play the game properly.

Call of Duty: Warzone is a free-to-play battle royale video game released in March 2020 and developed by Infinity Ward, Raven Software, and Treyarch. The game is part of the 2019 title Call of Duty: Modern Warfare and can be played on Microsoft Windows, PlayStation 4/5, and Xbox One.

The second title of the series, Call of Duty: Warzone 2, was released in November 2022 and, despite its mixed reception by the players, remains one of the most popular battle royale games out there. Just like many modern AAA games, it suffers from some technical issues, and it is not all related to in-game bugs or glitches.

DEV ERROR 5573 is an error code that some players might encounter when playing both Warzone games. This error occurs when the game is unable to access certain data that it needs in order to function properly. Essentially, this error is preventing players from playing the game as normal. Fortunately, there are a few steps that can be taken to try and fix this issue.

To ensure that you are playing Call of Duty: Warzone with the best possible performance, it is essential to make sure your system is up-to-date. First and foremost, verify that you have the most recent version of the game installed on your PC.

Additionally, evaluating any new updates for both DirectX software and graphics card drivers can help avoid compatibility issues; similarly, Windows updates should be checked as they could also influence gameplay. If these steps do not solve the problem at hand, reinstalling and then trying again may bring about a successful outcome.

While we provide all the manual solutions for the DEV ERROR 5573 error in COD: Warzone, we recommend running a quick scan with an automatic PC repair tool [d1], which can remove any inconsistencies on the system and repair any damaged components quickly for you.

Method 3. Remove some in-game items

To prevent the error code from appearing, be sure to remove any Cold War items, such as FFAR and Pellington, from your Call of Duty: Warzone arsenal. These are two guns that have been known to trigger this issue in particular. By ensuring these weapons are removed from your collection, you can ensure a smooth gaming experience free of technical issues.

Method 4. Run the game with DirectX11

Some users reported that launching the game with DirectX11 instead 12 helped them to avoid DEV ERROR 5573:
