Well, playing private matches can help players to practice aiming, improve map awareness, etc apart from having fun with friends most of the time.

1. Run MWII in Safe Mode

First of all, you should try running the COD Modern Warfare II game in Safe Mode because you may encounter the mentioned dev error while trying to play a private match.

For Steam:

Open the Steam client > Go to Library.
Click on COD Modern Warfare II from the list of installed games on the left pane.
Now, the client will automatically search for the available update.
If there is an update available, click on the Update option.
Wait for a couple of minutes or so until the game update completes. [Depends on the storage space and internet connectivity]
Once done, make sure to close the Steam client.
Finally, reboot your PC to apply changes, and launch the game again.

For Battle.net:

Open the Battle.net (Blizzard) launcher.
Click on the Blizzard logo from the top left corner.

It should automatically update the game to the available version.

5. Verify and Repair Game Files

Sometimes corrupted or missing game files on the PC may trigger some issues with the game launching or running smoothly. Make sure to verify the game files and repair them via the Steam or Battle.net client by following the steps below:

For Steam:

Open the Steam client on the PC and log into the account.
Go to Library > Right-click on the COD MWII game.
Click on Properties > Click on the Local Files tab.
Click on Verify Integrity of game files…

6. Check for Online Matchmaking

Plenty of affected players have reported that retrying the online matchmaking process and canceling it multiple times did fix the issue. Once done, just wait for a while, and try playing a private match again, and it should work fine.

7. Don’t Use VPN

Last but not the least, it’s highly recommended not to use any VPN service on your PC or router to avoid networking glitches whatsoever. VPNs generally can connect you to a different region server but it won’t help in improving latency or ping delay. The higher the ping delay your game server will receive, the more you’ll face errors in connecting to the game.
