How to Fix PS4/PS5 Error CE-34878-0 (Game Crashed)

CE-34878-0Plain English: the game crashed unexpectedly. It's PlayStation's generic "the application stopped working" error — the cause is usually corrupted game data or outdated software, not a dead console.
Quick answer: CE-34878-0 means a game crashed on your PS4 or PS5. Close and relaunch the game first — many crashes are one-offs. If it keeps happening, do a full power cycle, update both the game and the system software, then rebuild the database in Safe Mode. Reinstall the game (after backing up saves) as the final fix.

What error CE-34878-0 means

CE-34878-0 is the most-seen error code in PlayStation gaming, and also the least specific. It is the console's generic application-crash report: the game encountered something it could not handle — a corrupted data file, a memory conflict, a mismatched system call — and the operating system terminated it. The code itself does not identify which of those happened, which is why the fix is a process of elimination rather than a single magic button.

The reassuring part is that this error is overwhelmingly software-related. In the large majority of cases, the console hardware is perfectly fine; the crash comes from the game's own files, the system software version, or the drive's file index getting tangled. That is why the fixes below start with the trivial (relaunch the game) and escalate only as needed. Only when every game on the system crashes — even after a database rebuild and fresh installs — should you start suspecting the storage drive itself.

Common causes

How to fix error CE-34878-0 — step by step

Work through these in order. Do not reinstall the game until you have backed up your saves (step 5).

  1. Restart the game. Close the crashed game completely rather than just suspending it. On PS5, press the PS button, highlight the game on the home screen, press the Options button, and choose Close Game. On PS4, hold the PS button and choose Close Application. Then launch the game again. A surprising number of CE-34878-0 crashes are single memory glitches — if the game runs fine now, you are done.
  2. Do a full power cycle. If the crash repeats, shut the console down completely — not rest mode. On both PS4 and PS5, hold the power button until the system powers off, then unplug the power cable from the back of the console. Wait a full 60 seconds, plug it back in, and power on. This drains residual power and clears the system cache, fixing crashes that survive a normal restart.
  3. Update the game and the system software. Outdated software is a top crash trigger. Highlight the game on the home screen, press Options, and choose Check for Update, then install anything available. Next, update the console itself: on PS5 go to Settings, then System, then System Software, then System Software Update and Settings; on PS4 go to Settings, then System Software Update. Install the latest firmware and restart before testing the game again.
  4. Rebuild the database in Safe Mode. This is the heavyweight fix for corrupted system data, and it deletes nothing. Power the console fully off. Then press and hold the power button until you hear two beeps (about seven seconds) — the console boots into Safe Mode. Connect your controller with a USB cable and press the PS button. Choose Rebuild Database and let it run; it can take several minutes to over an hour on a full drive. This reorganizes the file index and repairs the corrupted entries behind many recurring crashes.
  5. Back up your save data. Before the final step, protect your progress. On PS5, go to Settings, then Saved Data and Game/App Settings, then Saved Data (PS5) or Saved Data (PS4), and upload to cloud storage (requires PlayStation Plus) or copy to a USB drive. On PS4, go to Settings, then Application Saved Data Management, then Saved Data in System Storage, and copy to online storage or USB. Verify the backup exists before continuing.
  6. Reinstall the game. Highlight the game, press Options, and choose Delete — this removes the game files but your backed-up saves are safe. Restart the console, then reinstall: insert the disc, or find the game in your Library and re-download it. A completely fresh install replaces every game file, eliminating corruption the earlier steps could not reach. Restore your saves from the cloud or USB afterward and test.

Did this fix it? Quick checklist

If only one specific game crashes while everything else is fine, check that game's community forums — some crashes are bugs in the game itself that only a developer patch can fix. Keep the game updated and report the crash with the error code. If every game crashes even after a database rebuild, back up everything and consider a full console initialization or professional service for the storage drive.

Frequently asked questions

What does PlayStation error CE-34878-0 mean?

CE-34878-0 is PlayStation's generic application-crash error — it means a game or app stopped unexpectedly. It does not point to one specific fault; corrupted game data, outdated software, a cluttered database, or failing storage can all produce it.

Will I lose my save data fixing CE-34878-0?

Not if you follow the steps in order. Restarting, power cycling, updating, and rebuilding the database all preserve saves. Only a game reinstall risks saves stored locally, which is why backing them up to the cloud or USB first is essential.

Does CE-34878-0 mean my PS4 or PS5 is dying?

Usually not. The error is overwhelmingly software-related — corrupted game files or system data. But if every game crashes with CE-34878-0 even after a database rebuild and fresh installs, the console's storage drive may be failing and worth having serviced.

What is Safe Mode on PlayStation?

Safe Mode is a diagnostic startup state. Power the console fully off, then hold the power button until you hear a second beep (about 7 seconds). Connect the controller via USB cable and press the PS button. From its menu you can rebuild the database, update system software, or reset the console.
