When a game crashes on PlayStation 4, you will normally get sent to the PlayStation 4 dashboard and receive one of the following error messages:

1. Error code CE-34878-0.
2. An error has occurred with an application or system software.

If you receive either of these error messages, simply restart the game and attempt to play again. However, if you continue to receive either of these error messages, there are measures you can take to reduce the chance of game crashes.

Is your system software up to date?

The best way to avoid game crashes or freezing is to make sure the software on your PlayStation 4 is up to date. Follow these steps to check for updates:

1. Select the Home button in the center of the controller.
2. Scroll up and select Settings.
3. Select System Software Update.

Is everything else in good working order?

If your PlayStation 4 is up to date, try the following troubleshooting tips:

• Check your game disc for abrasions, scratches, or dust. If the disc is dirty, clean it with a soft cotton cloth dampened with water. Wipe the non-label side from the center straight out to the edges. Be sure your disc is completely dry before inserting it back into your PlayStation 4.
• Ensure your PlayStation 4 console is in a cool, well-ventilated place.
• Delete old files and game data from your PlayStation 4.
• Try the game on another PlayStation 4. If the same problem occurs on another PlayStation 4, the problem is most likely with the game disc itself. If this is the case, you can request a replacement game disc.

Please note: Activision cannot guarantee functionality on PlayStation consoles using 3rd party hardware. This includes, but is not limited to, memory cards, controllers, chips, and cables.

You've ruled everything out. Now what?

If your PlayStation 4 is up to date and in good working order, there might be an issue with your PlayStation 4 console. Please contact PlayStation Support for assistance.
