  1. Open your Battle.net client.
  2. From the left menu, select Call of Duty: MW . Click Options and select Scan and Repair .
  3. Click Begin Scan . Then wait for the checking to complete.
  4. Once done, enter the game and play as you normal would.

Fix 2:Update your graphics driver

Crashes in COD series are usually graphics-related — It could mean your game encountered a compatibility issue triggered by abroken or outdated graphics driver . That’s why we always recommend gamers to keep their drivers up to date: new drivers improve your gaming experience and most importantly, they would also fix compatibility issues like lagging and constant crashing.

There’re mainly 2 ways you can update your graphics driver: manually or automatically.

Option 1: Update your graphics driver manually

If you’re a tech-savvy gamer, you can spend some time updating your GPU driver manually.

To do so, first visit the website of your GPU manufacturer:

Then search for your GPU model. Note that you should only download the latest driver installer that’s compatible with your operating system. Once downloaded, open the installer and follow the on-screen instructions to update.

If you don’t have the time, patience or computer skills to update your video drivers manually, you can, instead, do it automatically withDriver Easy . Driver Easy will automatically recognize your system and find the correct drivers for your exact graphics card, 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 Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.(This requires the Pro version – you’ll be prompted to upgrade when you click Update All.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.)
    NeoDownloader - Fast and fully automatic image/video/music downloader.

The Pro version of Driver Easy comes with full technical support . If you need assistance, please contact Driver Easy’s support team at [email protected] .

After updating your graphics driver, restart your PC for it to take full effect. Then join a game in Warzone and test the gameplay.

If the latest GPU driver doesn’t stop the crash, you can try the next fix below.

Fix 3: Install all Windows updates

Microsoft rolls out Windows updates periodically, which includes security patches and some nice-to-have new gimmicks. In addition to drivers, you should alsomake sure your system is up to date so as to avoid some strange issues.

Here’s how you can check for updates manually:

  1. On your keyboard, press Win (the Windows logo key). At the bottom left corner of your screen, click thegear icon to open Settings.
  2. Scroll down and selectUpdate & Security .
  3. ClickWindows Update .
  4. ClickCheck for updates . Then wait for the process to complete. After that, restart your PC.

To make sure you’ve installed all the system updates, repeat these steps until it prompts “You’re up to date” when you click Check for updates again.

Once you’ve installed all the Windows updates, restart your PC and check if error has disappeared.

If Warzone crashes with the same error again, you can try the next method below.

Fix 4: Reinstall all shaders

Shaders refer to a type of program used largely for rendering of different pixels. Some players reported thatreinstalling shaders could be a potential fix for the dev error, so you can try the same and see if it helps.

To do this, simply follow these steps:

  1. Launch Modern Warfare and go toOptions .
  2. Navigate to theGRAPHICS tab. ClickRestart Shaders Installation .
    PaperScan Professional: PaperScan Scanner Software is a powerful TWAIN & WIA scanning application centered on one idea: making document acquisition an unparalleled easy task for anyone.
  3. ClickRESTART to proceed.
  4. Wait for the process to complete. Then restart your game and test the gameplay

If reinstalling shaders doesn’t give you luck, simply move on to the next fix.

Fix 5: Change your loadouts, skins and operators

The dev error could also be a glitch inside the game. According to some players, changing to Modern Warfare loadouts seemed to have stopped the error from appearing. So if you’re usingloadouts or operators from Black Ops Cold War, change them to the Modern Warfare ones and check the outcome. In the meantime,remove all your skins .

BOCW Operators

For the full list of BOCW operators, you can check outthis page .

If this trick doesn’t stop the crash, check out the next fix below.

Fix 6: Change to another account

There’s also feedback showing that the dev error 6634 issue might be limited to certain accounts. So if possible, considertesting another account on the same computer . If the problem disappears after changing the account, then you need to compare the difference between two accounts, including but not limited to loadouts, skins and operators.
