So far, the team at Activision hasn’t been able to provide any solid reason for why dev error 6328 appears. With that said, some users have been able to fix the problem by restarting their system, their router, or by updating their Nvidia Studio software.

Unfortunately, none of these fixes seem to work in every situation. 6328 remains one of the more frustrating problems in both Warzone and Modern Warfare since it seems to have no clear solution. However, it’s at least worth trying a few of the suggestions below in the off chance they’ll fix the issue.

  • Restart your computer or console
  • Power cycle your modem and/or WiFi router
  • Make sure your graphics card drivers (and specifically your Nvidia Studio software) are up to date
  • Ensure that Windows has the latest update package installed
  • Use the Scan and Repair tool through the launcher

No one is really sure what the Call of Duty: Warzone and Modern Warfare dev error 6328 means. As such, there’s no guaranteed way to fix it. The small number of players who have managed to circumvent the error most often report that a system or router restart seems to have done the trick. If that doesn’t work, it’s worth opening up a support ticket with Activision Support.
