    update & security

Fix 3: Update your graphics driver

There’re multiple reports suggesting that the dev error 5573 is graphics-related. In other words, it could indicate that you’re using a faulty or outdated graphics driver. If you don’t remember when was the last time you checked for drivers update, definitely do it now because it could just fix the problem up in a jiff.

So there’re 2 ways you can keep your GPU driver up to date: manually or automatically.

Option 1: Update your graphics driver manually

If you’re familiar to your computer hardware, you can try to update your graphics driver manually. First you need to visit your graphics card manufacturer’s website and search for your model:

Then download the correct installer that’s compatible with your operating system.

If you don’t have the time, patience or computer skills to update your GPU driver manually, you can, instead, do it automatically with Driver Easy. Driver Easy will automatically recognize your system and find the correct drivers for all your hardware, and your Windows version, and it will download and install them correctly:

  1. Download and install Driver Easy.
  2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
  3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.
    (This requires the Pro version – you’ll be prompted to upgrade when you click Update All. If you don’t want to pay for the Pro version, you can still download and install all the drivers you need with the free version; you just have to download them one at a time, and manually install them, the normal Windows way.)
The Pro version of Driver Easy comes with full technical support. If you need assistance, please contact Driver Easy’s support team at support@drivereasy.com.

Once you’ve updated all your drivers, restart your PC and see if Warzone crashes again.

If the latest drivers didn’t help you, simply continue to the next fix.

Fix 4: Perform a clean boot

In order to further rule out any possible interference, you need to perform a clean boot to make sure your system is free of compatibility issues. It means you need to start your PC with only the essential software and services.

  1. On your keyboard, press Win+R (the Windows logo key and the r key) at the same time to invoke the Run box. Type or paste msconfig and click OK.
  2. In the pop-up window, navigate to the Services tab and check the box next to Hide all Microsoft services.
  3. Uncheck all the services EXCEPT those belong to your graphics card and sound card manufacturers, such as RealtekAMDNVIDIA and Intel. Then click OK to apply the changes.
  4. On your keyboard, press CtrlShift and Esc at the same time to open Task Manager, then navigate to the Startup tab.
  5. One at a time, select any programs you suspect might be interfering, and click Disable.
  6. Restart your PC.

Now you can join a match and see if the error pops up again.

If this trick doesn’t do the trick for you, move on to the next one.

Fix 5: Rebuild your settings

Some gamers verified that deleting the user config files will cause the game to reset and thus solve the issue. You can try the same using the following steps:

  1. On your keyboard, press Win+R (the Windows logo key and the r key) to open the Run dialog. Type or paste %USERPROFILE%\Documents and click OK.
  2. Delete all files inside the folder named Call of Duty Modern Warfare/Call of Duty. (Leave the folder empty.) Then launch Warzone and check if the problem persists.

If this trick doesn’t give you luck, simply continue to the cross-platform solutions below.

Fixes for PC & console

The following fixes apply to both PC and console.

Fix 1: Change to Windowed mode

According to the feedback, changing in-game settings to Windowed mode could be a potential fix to the crash. So you can try this and see how things go.

To do this, go to OPTIONS > GRAPHICS. Under the DISPLAY section, set Display Mode to Windowed.

If changing the display mode doesn’t solve your problem, you can try the next method.

Fix 2: Switch to another account

According to some, the Dev Error 5573 only appears on certain accounts. So if possible, you can switch to another account, then check if the crash happens again. If the problem disappears, you can contact the Activision support for further troubleshooting regarding your account.

If the issue lingers on, take a look at the next solution.

Fix 3: Switch to Modern Warfare operators

If you’re using an operator from Black Ops Cold War, you can try another one from Modern Warfare. Some users reported that the error disappeared when using operators that are not from Black Ops Cold War. It’s unclear whether it’s just a glitch or a compatibility issue.
