CE-34878-0
Sony PlayStation
Severity: ModerateWhat Does This Error Mean?
The CE-34878-0 error means an application or game has crashed on your PlayStation. This is one of the most common PS4 and PS5 errors. It can be caused by corrupted game data, outdated software, or a temporary system glitch.
Affected Models
- PlayStation 4
- PlayStation 4 Slim
- PlayStation 4 Pro
- PlayStation 5
- PlayStation 5 Digital Edition
Common Causes
- The game or application has a bug that causes it to crash
- The game data on your hard drive has become corrupted
- Your PlayStation system software is outdated
- The hard drive is failing or running very low on free space
- A recent system update introduced an incompatibility with the game
How to Fix It
-
Close the crashed application completely. Press the PlayStation button, highlight the game, press Options, and select 'Close Application.'
Do not just leave it in the background — fully close it before relaunching.
-
Check for game updates. Highlight the game on the home screen, press Options, and select 'Check for Update.' Install any available updates.
Developers often release patches to fix crashes. Running an outdated version is a common cause.
-
Check for system software updates. Go to Settings > System Software Update and install any available updates.
System updates improve stability and fix compatibility issues with games.
-
If the error keeps happening in one specific game, delete and reinstall it. Go to Settings > Storage, find the game, and delete it. Then redownload or reinstall from disc.
Your saved game data (progress, saves) is stored separately and will not be lost.
-
If the error happens across multiple games, rebuild the database. Turn off the PS4/PS5, then hold the power button for 7 seconds until you hear a second beep. Select 'Rebuild Database.'
This reorganizes your hard drive data without deleting anything. It can take a few hours.
When to Call a Professional
If the CE-34878-0 error happens in every game and not just one, your PlayStation's hard drive may be failing. A hard drive replacement costs $50 to $100 for the part, plus labor if you need a technician. You can also replace the hard drive yourself using a guide from PlayStation's support website.
Frequently Asked Questions
Will I lose my saved game data if I reinstall a game?
No. Game save data is stored separately from the game itself. Deleting and reinstalling a game only removes the application files, not your saves. However, it is always a good idea to back up saves to the cloud (PS Plus) or USB just in case.
Why does CE-34878-0 only happen in one specific game?
The game files on your hard drive may be corrupted. Or the game itself may have a bug that the developer needs to patch. Reinstalling the game fixes corrupted files. For bugs, check online if other players report the same issue.
What is 'Rebuild Database' and is it safe?
Rebuilding the database is like defragmenting a computer hard drive. It reorganizes the data on your PlayStation's storage without deleting anything. It is completely safe and often fixes performance issues and crashes.
