Explanation
What this error means
CE-106485-4 is documented as “there may be a problem reading the system software or data.” The console hit trouble reading data it needed. A corrupted database or interrupted write is the common, home-fixable cause; a recurring case can point to storage that’s struggling to read reliably.

Diagnosis
Most likely causes
| Cause | How likely | Fixable at home? |
|---|---|---|
| Corrupted database or system index | Likely | Yes — rebuild in Safe Mode |
| Interrupted update or power loss | Likely | Yes — update / restart |
| Failing internal or M.2 storage | Possible | Sometimes — test / service |
| Transient read glitch | Possible | Yes — restart |
Repair
How to fix it
Ordered easiest-first. Try the next step only if the error comes back.
-
Restart the console
Power > Restart PS5. A clean boot clears most one-off read glitches.
-
Rebuild the database
Boot Safe Mode (hold power to the second beep), connect the controller by USB, and choose “Rebuild Database” — it reindexes storage without deleting games or saves.
-
Update the system software
Settings > System > System Software Update, or update from Safe Mode if the system won’t reach it normally.
-
Test M.2 storage separately
If problems track to games on an added M.2 SSD, move one to internal storage and compare; a stable internal copy points at the M.2 drive.
⚠ Power down fully and unplug before opening the M.2 expansion bay. Don’t open sealed sections of the console.
-
Reinstall the affected app
If it points to one game, delete and reinstall it for a clean copy.
Escalation
When it's not your fault
Signs the problem is on Sony's side — or in the hardware — rather than anything you can change:
- It appeared once after a power cut or interrupted update, then didn’t return.
- A rebuild clears it cleanly — a sign it was a corrupted index, not hardware.
- It only affects one app whose latest patch others also report problems with.
Questions
FAQ
Is my SSD failing?
Not necessarily — a corrupted index or interrupted write is more common, and a rebuild often fixes it. Recurrence across many apps after clean rebuilds is what points to storage.
Does rebuilding delete data?
No. Rebuild Database keeps games and saves; it only reindexes storage.
Could my M.2 drive be the cause?
If errors only affect games on the M.2 SSD, compare against internal storage; a stable internal copy suggests reseating or testing the M.2 drive.
