How to Fix Modern Warfare Multiplayer Not Working

Some people could not access it, saying that they either get brought to Warzone or that they are prompted to repurchase the game, which they already own. In such cases, licensing issues, missing multiplayer packs, or cache data can serve as culprits for such occurrences.

Call of Duty: Modern Warfare multiplayer isn't working

You mightn't be able to access several modes of the game because of corrupted cache, missing packs, or an invalid license, or the system might not recognize your game as owned. Grateful that the causes are out of the way, now, how to fix it. 1. If applicable, launch Call of Duty: Modern Warfare as a standalone game.

Opening Modern Warfare and Warzone separately avoids the mistake of them opening at the wrong time because such a situation needs to be avoided in order to avoid confrontations. This step, therefore, prioritizes the right game files to avoid problems caused by shared launchers.

Fortunately, a fix has been discovered that is compatible with both consoles and PCs: Use the game's dedicated launcher and run it independently of Call of Duty: Cold War.

Activating Call of Duty: Modern Warfare with Call of Duty: Cold War is not right.

If this bug occurs, do not launch Call of Duty: Modern Warfare through the Cold War launcher.

Instead, it should be launched through the game's official launcher. This has been confirmed to work for both PCs and consoles.
