Why Warzone Keeps Crashing on PC (And How to Fix It in 2026)
If Warzone keeps crashing on PC, first check whether Activision is tracking a current game issue, then work through your Windows, graphics driver, game files, and background software. Most repeat crashes are tied to a patch or shader-preloading problem, an unstable or outdated driver, damaged game files, heavy graphics settings, or another program interfering with the game. Use the six fixes below in order and stop once the game is stable.
This guide focuses on the Windows PC version of Call of Duty: Warzone. Menu labels can shift with game and launcher updates, so use the current options in your installed version. Activision's PC troubleshooting page is dated March 11, 2026, and its live Known Issues page should be checked before you spend time reinstalling.
Why does Warzone keep crashing?
A crash can come from the game itself or the PC running it. A newly released update can introduce a bug that affects many players; a local crash may instead trace to a graphics driver, incomplete game files, an unfinished shader-preloading pass, an overworked graphics card, unstable overclock settings, or a conflicting overlay or utility. A game that closes to desktop or displays a dev error is different from a match disconnect: a disconnect can be network or server related without the game actually crashing.
Activision's current PC guidance specifically recommends keeping Windows and graphics drivers current, allowing shader preloading to finish, repairing files through Battle.net or Steam, and closing applications that can conflict with Warzone. It also lists a few utilities that may interfere. Check the Warzone Known Issues page first if the problem began after a seasonal or mid-season update.
Before troubleshooting
- Write down the exact error code and when the crash happens: during launch, while loading a map, or mid-match.
- Check for a pending Call of Duty update and restart the PC once before changing settings.
- After a game or graphics-driver update, stay at the main menu and let shader preloading finish. Activision warns that leaving the menu early stops the process and can cause performance problems.
- Change one thing at a time. If a crash stops, you will know which fix helped.
How to fix Warzone crashing: six steps
-
1. Update your graphics driver from its official source
An outdated or unstable GPU driver can cause launch failures, visual errors, and crashes during a match. Open the software for your graphics card and check for a driver update, or download the correct driver directly from NVIDIA, AMD, or Intel. Choose the package for your exact card and Windows version. Laptop owners should also check the laptop maker's support page if its graphics hardware uses a customized driver.
Restart Windows after installing the driver, then launch Warzone and let shaders preload. Do not rely on a generic driver-updater utility or copy a driver version from an old forum post; Activision's driver guidance can vary by GPU family and device type.
-
2. Repair Warzone's installed files
Missing or damaged files can make Warzone crash at startup or during play. In Battle.net, open the Call of Duty page, choose the gear or options menu beside Play, and select Scan and Repair. In Steam, open your Library, right-click Call of Duty, choose Properties, open Installed Files, and select Verify integrity of game files. Let the check finish before starting another download or repair.
Steam notes that a small number of files may fail verification because they are local configuration files that should not be replaced; that result by itself does not always mean the repair failed. See Steam's verification instructions or Activision's PC troubleshooting steps for the launcher-specific guidance.

3. Install Windows updates and check available storage
Open Settings > Windows Update, check for updates, install the available updates, and restart if prompted. Keep some free space on both the Windows drive and the drive holding Call of Duty so updates and temporary files have room to complete. You do not need to delete personal files blindly; use Windows Storage settings or uninstall apps you recognize and no longer use.
Activision's Warzone PC page lists Windows 10 and Windows 11 as supported. Microsoft ended free Windows 10 updates and security fixes on October 14, 2025, so check Microsoft's current guidance if your PC still runs Windows 10. That support change is not proof that Windows is causing a particular crash, but an outdated system can miss fixes. Microsoft's Windows Update instructions explain how to check and install updates.

4. Reduce graphics load and let shaders finish
If Warzone crashes after a few minutes or only in demanding scenes, restore graphics settings to their defaults and lower them gradually. Start with texture quality or texture resolution, then reduce other demanding options available in your current build. If your version includes ray tracing and you have it enabled, turn it off as a test. Avoid changing several settings at once; launch the same mode again so you can tell whether the change mattered.
After a game patch or driver change, return to the main menu and wait for shader preloading to complete before queueing for a match. Activision identifies this as part of the first-boot process and says leaving the menu interrupts it. Setting names and available graphics options change, so follow the options shown in your current Warzone version rather than instructions written for an older release.
-
5. Close overlays and test for software conflicts
Temporarily close game overlays, recording or streaming tools, hardware-monitoring utilities, and other nonessential programs, then relaunch Warzone. Activision specifically calls out NZXT CAM, MSI Afterburner, and Razer Cortex as possible conflicts, and advises updating Razer Synapse. If you use a CPU or GPU overclock or undervolt, return that component to its normal settings for a test; instability can show up only under a demanding game workload.
Use Task Manager to close apps you recognize, but do not end unfamiliar Windows processes or disable security protection just to test a game. If security software reports a specific Warzone file, verify that the game came from the official launcher and follow the security vendor's instructions before allowing it. If closing ordinary apps does not isolate the problem, Activision links to a Windows clean-boot procedure for advanced troubleshooting.

6. Reset settings, then reinstall only as a last resort
If crashes continue, reset the game's graphics settings to their defaults and run the launcher repair again. After a patch or driver update, let shader preloading complete again; avoid deleting system or driver cache folders based on generic instructions, because the right procedure depends on the driver and game version.
Reinstall Warzone only if the first five steps and a settings reset have not helped. Use the launcher to uninstall and install the game again, confirm the download has completed, restart the PC, and allow shaders to preload before playing. A reinstall takes time and bandwidth, so check Activision's Known Issues page first if the crash started immediately after a new update.
Match the symptom to the next step
| What happens | What to try next |
|---|---|
| Warzone closes before the menu appears | Check Known Issues, update the GPU driver, then scan or verify the game files. |
| The game freezes or closes mid-match | Lower texture settings, close overlays and monitoring apps, and test with overclocks returned to stock. |
| Crashing began after a game or driver update | Finish shader preloading, restart the PC, and check the current issue tracker before reinstalling. |
| A dev error appears every time | Record the exact code, repair the files, and search the official Known Issues page for that error. |
If the whole PC restarts, shows a blue screen, or loses power rather than only closing Warzone, investigate Windows, hardware, and temperatures as well; that pattern can involve a wider system problem.
When to report a Warzone crash
If the game still crashes after these checks, send Activision the exact error code, the point in the game when it occurred, your graphics-card model, and whether the issue began after a specific update. Activision's voluntary PC Crash Report form accepts crash details and log files to help investigate PC crashes. A report is useful even when the live issue page does not yet list your particular symptom.
Frequently asked questions
Should I reinstall Warzone as soon as it crashes?
No. Check for a known game issue, update the driver, repair the files, and test lower settings first. Reinstalling is a large download and will not fix a bug affecting the current game build.
Why does Warzone crash after an update?
A patch can introduce a game-side bug, leave an update incomplete, or trigger shader preloading. Confirm the update finished, stay in the main menu until preloading completes, restart the PC, and check Activision's issue tracker for a tracked problem.
