A Reddit post dated December 1, 2022, says changing a Windows registry priority value for cod.exe stopped the author’s game_steam_ship.exe crashes. That is one player’s reported workaround—not an Activision fix or a proven solution for other PCs. Start with Activision’s current troubleshooting steps; treat the registry edit as an older, unverified suggestion.
What is the “working fix” for this error?
The post’s proposed change sets CpuPriorityClass to 00000003 under the Windows Image File Execution Options entry for cod.exe. The author says it stopped their crashes. The post does not establish why that PC crashed, whether the change caused the improvement, or whether it will help another player. Read the original Reddit post.
This is a registry modification, not an official Activision instruction. Because it changes Windows configuration and the post is from 2022, do not treat it as a guaranteed or verified fix for current Warzone builds. The source does not provide controlled testing or a success rate.
What should you try first?
Activision’s PC guidance recommends checking Windows support and updates, confirming the PC meets the game’s minimum requirements, using applicable graphics drivers, and submitting a PC Crash Report if the problem persists. Its reviewed troubleshooting page does not document a specific remedy for the exact 0x00001338 (0) N signature. See Activision’s Warzone PC troubleshooting guidance.

- Check Windows. Activision lists Windows 10 and Windows 11 as supported and recommends keeping a supported version current.
- Check minimum requirements. Compare your PC with the requirements on Activision’s live support page, which can change.
- Check graphics drivers. Use the driver guidance applicable to your graphics hardware, as linked from Activision’s page.
- Report the crash. If the game continues to crash, submit Activision’s PC Crash Report so the issue can be investigated.
Does the error code identify one cause?
No single cause or universal fix is established by the code alone. Community discussions around the registry suggestion include different hardware and software experiences, and another game_steam_ship.exe discussion describes a different numeric error variant. Those reports illustrate that outcomes vary; they do not diagnose your PC. See the Steam discussion of the workaround and the separate Steam discussion of game_steam_ship.exe.
Should you edit the registry?
The cited post describes adding or changing a value at HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionImage File Execution Optionscod.exePerfOptions, with CpuPriorityClass set to 00000003. Consider it only as a user-reported suggestion, not as an official, validated troubleshooting step. If you are not comfortable changing Windows registry settings, skip it and use Activision’s support route instead. The cited sources do not establish that this change is safe or effective for current game builds.
