Dev Error 6634 is one of the most dreaded errors in Call of Duty: Black Ops. You can avoid it by removing any Cold War cosmetics that you may have equipped.

Many have found that changing loadouts from the Black Ops: Cold War to the Modern Warfare seemed to fix the issue — if you are using Cold War loadouts or operators, try switching them to Modern Warfare ones. Also, remove all of your skins.
Solution 2. Fix Warzone Dev Error 6634 by Updating Your Graphics Driver
Graphics drivers are among the most important elements of any gaming system, and GPU-intensive tasks like gaming can be easily hindered by outdated software which can causes compatibility issues in the first place.

To stop this from happening, we always recommend gamers to keep their drivers up to date. A newer driver ensures stability and the best possible performance for your gaming rig.

Solution 3. Verify Integrity of Game Files on Steam
Malfunctioning software can create a number of issues — corrupted files, pieces of hardware that don’t work correctly, and repeated crashes. When an error occurs in your game, it could be a problem with the integrity of the files. Scanning for integrity means locating these corrupted files so that you can then fix them.
This can occur for several reasons, one of which is the downloading of corrupted files. If you suspect this to be the cause of your crash, start by scanning and repairing your game’s files. This can be done by following these steps:

Solution 4. Update Windows To The Latest Version
It’s important to keep your computer up to date with the latest Windows updates. The latest version of Windows is often the greatest, with a slew of new features and functions to help you do more within a device that’s constantly on the go. These updates ensure that you’re using the latest version of Windows, which includes the latest drivers and other system features.

Solution 5. Test Account To Fix Warzone Dev Error 6634
In rare cases, the dev error 6634 may happen because of certain accounts. This can be an issue with your specific account and not necessarily a bug in the game. If changing accounts also fixes the problem, compare both accounts to see what can be causing the error. It may be that you have a particularly buggy profile or a loadout that causes problems.
Solution 6. Restart Shaders Installation
Restarting the installation of the Warzone shader might fix the Dev Error 6634. Shaders are responsible for rendering graphics, so restarting the shader service might help fix the issue.
To restart them, follow these steps.
- Start COD Warzone and select Options. Next, click GRAPHICS.
- Next, click Restart Shaders Installation, and then click RESTART.
- Allow the process to complete.
- Now, restart your game and see if the problem still exists.
Solution 7. Free up your RAM and VRAM
Warzone is a demanding game, to say the least. It is a very resource intensive game by design and Players will often find their systems running slowly or even freezing during gameplay. If players are running it for an extended period of time, they may notice that their computer’s performance slows down or drops. This is usually caused by memory leaks – if Warzone overdraws video memory, it can leave images in VRAM. As you keep playing, it becomes harder and harder for your PC to clean this up, as there’s only so much memory a system can have.
So, if you’re experiencing the dreaded Dev Error 6634, it may be due to your RAM or VRAM being full. An excellent way to solve any performance issues that players experience is by restarting the game. This will reset the game’s memory usage and help avoid crashes.
Solution 8. Reinstall COD: Warzone
This is not a good method for most Warzone players to troubleshoot because of the sheer size of the game. While it’s not something players necessarily look forward to, installing Warzone and starting from scratch is a fairly effective troubleshooting method for minimizing issues during gameplay. Since it clears out your game files and resets your settings, the issue you’re experiencing may just be a relic of a previous run-through or corrupted files that are no longer compatible with the current version of the game. While it does take a long time to download Warzone and any updates, it’s an excellent way to make sure that error isn’t appearing due to corrupted game files.
