[Solved] COD Modern Warfare Dev Error 6328

The latest Call of Duty release (Modern Warfare) is surrounded by a lot of controversies. The game was riddled with bugs & issues upon its release, and some of them are still wreaking havoc among the PC player base, months after it’s release. One of the most common issues of this kind is Dev Error 6328, which typically occurs when the player attempts to start the game or when waiting in the Multiplayer lobby.

When dealing with this issue, the first fix you should try is to restart your computer along with your router or modem. If that doesn’t work, try disabling the two background Origin services in case you’re launching the game through Origin. On the other hand, if you’re launching the game through Battle.net, clear the cache folder located in ProgramData instead.

In case you’re using an Nvidia GPU, you can try installing the latest Studio driver (some users have reported that this has resolved the issue for them). And in case you are only encountering the Dev Error 6328 when you attempt to join a multiplayer game, try forcing the game to run in borderless mode with VSync on
