Solution 1: Uninstall the MutiPlayer Pack 2 and MultiPlayer Pack 3 (Consoles Only)

You should check to see if the issue is related to a common cause of a broken MultiPlayer Pack 2 or MultiPlayer Pack 3 content.

If the first potential fix was unsuccessful in your instance and you determined that Cold War content is not related to this mistake.
