What Does Warzone’s Dev Error-5573 Mean?
The issue is reportedly very noticeable on the game’s PlayStation and PC ports. Throughout the PS5 version of the game, the problem is still persistent. However, explaining and fixing it is essential.
It is one of the game’s fatal faults and is frequently brought on by damaged game files or other game data. In most cases, it renders the game impossible to play. This is why the error can be compared to other game-breaking bugs like the Error Code Diver and the Error Code Vivacious.
These significant game-related difficulties have been the focus of ongoing efforts by Infinity Ward. However, the game has substantially improved due to the fixes and upgrades. As a result of its assets and other aspects, Call of Duty Warzone is prone to serious developmental problems.
Warzone Dev Error-5573: Possible Causes
We have carefully examined the precise causes of the game’s error. The game’s new connection to Call of Duty: Cold War is the primary source of the fundamental problems. The operators and firearms in both games are practically the same. Therefore, Dev Error 5573 Warzone is being made for the reasons listed below:
- Throughout a game, players may encounter the error multiple times. If so, speculate that a bandwidth problem might be the cause. You should test your Wi-Fi signal strength to determine if it is powerful enough, and if not, move on to increasing your bandwidth. Modifying your router’s settings or using an Ethernet connection are the best ways to improve it.
- Other players claim that a Cold War series Operator is also capable of making the mistake. You must switch to a Warzone operator as the active operator to avoid the problem, at least until it is fixed.
- Make sure there are no damaged game files before we move on to the fixes. This type of operation will differ on the PS4 and the PC.

How to Fix Warzone Dev Error 5573?
There will be a brief explanation of each fix in the guide’s appendices as to why it may resolve the problem. Let’s look at the many options to fix the Dev Error–5573 Warzone.
1- Check & Fix Corrupted or Missing Files
In addition to searching for updates or reinstalling, you can scan and repair any missing or damaged game files. It is a necessary choice in the event of a power outage or a sudden game shutdown. These conditions can damage the core files.
These core files are necessary for games like Warzone to operate correctly. They make up the majority of the game’s data. Without them, your game won’t even launch due to developer errors.
You may complete the process fairly quickly. When the game isn’t active, click on the “gear” icon in your library on the side. To update the game, access the drop-down menu.
By pressing “Scan and Repair” to recover any destroyed files, you can allow Battle Net to check for file verifications below it.
2- Windowed Mode Switching
Additional comments we got from the game’s Discord community support this. Players claim that altering the display modes can have a variety of effects on some of the error codes in the game.
Therefore, you should also provide the Dev error 5573. Although it is a straightforward remedy, it can benefit you in most other games in the market.
Windowed mode does not significantly reduce your system performance. There is no need to be concerned when using this display type.
Depending on the visual load and data, display modes differ from game to game. Updating the game’s resolution is the main advantage of switching the display mode to window. If all else fails, you are strongly advised to try this approach.
3- Changing Operators in a Warzone
The following technique was more of a flaw discovered by Warzone participants. You should refrain from using the game’s Operators, as was mentioned earlier in our causes for this mistake above.
You will be kicked out of the game when you try to play a match with “Dev Error-5573.” It will signify that you have caught the famed “operator glitch” in the game.
The operator menu will display the team tags for the Crossover operators from Black Ops Cold War.
The two Cold War operators, Garcia and Velikan, supposedly the most frequent ones to have glitches and give users in-game dev errors, should preferably be avoided by players.
Because of this, we advise players to stay away from them until Infinity Ward correctly publishes a patch to the game that corrects them. The operator bug in Warzone is present on both the PS4 and PC versions and can result in Dev Error-5573. To learn more about other Operators, look through our Season 3 Warzone Patch Notes.

- Use the Windows + X keys to open the Quick Start Menu.
- Double-click on Display Adapters after selecting Device Manager from the list.
- To use a dedicated graphics card, right-click on it.
