If you’re currently having issues playing Modern Warfare 3 or Warzone, you’re not alone. Many players are being hit by the dev error 5433 error code following the launch of Season Three Reloaded today.
How to fix dev error 5433 #callofduty #mw3 #mwz #warzone
The new season kicked off today at 11am CT, and players were quickly greeted with a gruesome code blocking them from doing anything in the game, including trying out the new BAL-27 assault rifle, new maps, the Zombies story mission, Warzone weapon balancing, and more.
This error pops up occasionally and is usually related to graphical issues in the game. However, since it’s been happening so often after the update, it’s likely something is broken and will need to be fixed by Activision in the hours after the update goes live.
The issue seems to be primarily affecting PlayStation players, so it's likely that a fix will need to be rolled out to the server. Unfortunately, there's not much players can do to fix the issue until the developer has fixed it.
