Warzone Modern Warfare Dev Error: Fixes That Work

If you’re seeing a “Dev Error” in Call of Duty: Warzone or Modern Warfare, it’s a crash caused by a corrupted game file, outdated drivers, or a conflict with background software—and you can usually fix it by updating your GPU drivers, scanning and repairing game files, and disabling overlays. This article explains the most common dev error codes, why they happen, and the exact steps to resolve them on PC, PlayStation, and Xbox.

What Is a Dev Error in Warzone/Modern Warfare?

Dev errors are crash reports that appear when the game’s engine hits an unexpected problem. They show a code like “Dev Error 6068,” “Dev Error 6328,” or “Dev Error 6036.” These errors can happen during a match, at the main menu, or when loading a map. They are not unique to one platform—PC, PlayStation, and Xbox players all see them, though PC players encounter them more often due to driver and hardware variability.

Common Dev Error Codes and Their Meanings

Dev Error 6068: Often related to DirectX or GPU memory issues. It usually appears when the game runs out of video memory or when the GPU driver crashes.
Dev Error 6328: A general crash that can be caused by corrupted shader cache or outdated graphics drivers.
Dev Error 6036: Typically linked to a corrupted game file or a problem with the game’s cache.
Dev Error 5573: Often appears on console and is usually fixed by restarting the game or console.

While the exact cause varies, the fixes below address the most common triggers.

How to Fix Dev Errors on PC

If you’re on PC, follow these steps in order. Most players resolve the issue with the first two steps.

Update your GPU drivers. Go to the NVIDIA or AMD website, download the latest driver for your graphics card, and install it. A clean install (using “Custom” and checking “Perform a clean installation” on NVIDIA) is recommended.
Scan and repair game files. In Battle.net, click the game, select “Options,” then “Scan and Repair.” In Steam, right-click the game, go to “Properties,” “Local Files,” and click “Verify Integrity of Game Files.” This replaces corrupted files.
Disable overlays. Turn off Discord overlay, GeForce Experience overlay, and any other in-game overlays. These can conflict with the game and cause crashes.
Lower graphics settings. Reduce VRAM usage by lowering texture resolution and turning off ray tracing. The game’s settings show a VRAM usage bar—keep it under 90%.
Clear the shader cache. In the game’s settings, go to Graphics and click “Restart Shaders Optimization.” If that doesn’t work, delete the shader cache folder in Documents\Call of Duty Modern Warfare\players (the folder name may vary).
Close background programs. Close browsers, streaming software, and other resource-heavy apps. Use Task Manager to end unnecessary processes.

How to Fix Dev Errors on PlayStation and Xbox

Console players have fewer variables, but dev errors still occur. Try these steps:

Restart the game. Fully close the game and relaunch it. This clears temporary cache files.
Restart the console. Power off completely, wait 30 seconds, and power back on.
Clear the console cache. On PlayStation, turn off the console, unplug it for 30 seconds, then plug it back in. On Xbox, hold the power button for 10 seconds to do a full shutdown.
Reinstall the game. If the error persists, uninstall and reinstall. This ensures no corrupted files remain.

Why Does the Dev Error Keep Happening?

Even after fixing the immediate crash, dev errors can recur. Common reasons include:

Outdated drivers: New game updates often require new drivers. Check for updates monthly.
Overheating: If your GPU or CPU runs too hot, the game may crash. Monitor temperatures with software like MSI Afterburner (PC) or check console ventilation.
Background downloads: Windows updates or game downloads can steal resources and cause crashes.
Corrupted shader cache: This can happen after a game update. Re-optimizing shaders often helps.

What to Do If the Error Persists

If you’ve tried everything and the error still appears, try these last-resort options:

Roll back your GPU driver. Sometimes the latest driver has bugs. Install the previous version from the manufacturer’s website.
Disable XMP/EXPO in BIOS. Memory overclocking can cause instability. Enter BIOS and set memory to default speeds.
Check for Windows updates. Install all pending updates, especially optional ones for hardware.
Contact Activision Support. If the error is widespread, they may have a fix or workaround. Check their official forums for known issues.

Frequently Asked Questions

Does a dev error mean my account is banned?

No. Dev errors are technical crashes, not bans. They have nothing to do with your account status.

Will reinstalling the game fix the dev error?

It can, but it’s a last resort. Reinstalling fixes corrupted files, but if the issue is driver-related, it won’t help. Try the other fixes first.

Is there a permanent fix for dev error 6068?

There’s no single permanent fix, but most players stop seeing it after updating drivers and lowering VRAM usage. If it persists, try the steps above.

Can dev errors damage my console or PC?

No. A dev error is just a crash. It won’t damage hardware. However, if your system is overheating, that can cause damage—so check temperatures if crashes are frequent.

Why does the game crash more after an update?

Game updates can change how the engine uses memory or graphics, which may expose bugs. Updating drivers and clearing shader cache usually resolves this.
