Marvel's Wolverine Save Corrupted or CE-34878-0 Crash — Fix & Recover on PS5

Last verified: 2026-09-23

If Marvel's Wolverine crashes to the PS5 home screen with error CE-34878-0 or tells you the save data is corrupted, don't delete anything yet — an un-backed-up PS5 save can't be re-downloaded. Here's the exact Console Storage location, how to upload a safe copy to PlayStation Plus cloud, rebuild the PS5 database to clear most crashes, and restore your progress the right way.

Save file

PS5 › Settings › Saved Data and Game/App Settings › Saved Data (PS5) › Console Storage

If Marvel's Wolverine crashes to the PS5 home screen with "Cannot start the application (CE-34878-0)" or says your save data is corrupted, do NOT let the game overwrite or delete anything yet. On PS5 your Wolverine save lives in Console Storage (Settings › Saved Data and Game/App Settings › Saved Data (PS5) › Console Storage › Marvel's Wolverine). First, if you have PlayStation Plus, upload that save to Cloud Storage so you have an untouched copy. Then rebuild the PS5 database in Safe Mode (this fixes most CE-34878-0 crashes without touching the save). Only if the game still reports corruption should you delete the single corrupt save and restore your good copy from Cloud Storage via Download/Sync. A PS5 save you have NOT backed up to PS Plus cloud cannot be re-downloaded — that is why the cloud upload is the real fix, done before anything else.

How to transfer your Marvel's Wolverine save to a new PC

Back up the save to cloud FIRST (PS Plus): Settings › Saved Data and Game/App Settings › Saved Data (PS5) › Console Storage › Upload to Cloud Storage, then select Marvel's Wolverine. This is your undo button — a PS5 save with no cloud copy cannot be re-downloaded if you delete it.
Rebuild the PS5 database (fixes most CE-34878-0 crashes, does NOT erase saves): fully power off the PS5, hold the power button until you hear the second beep to enter Safe Mode, connect the controller with USB, choose "Clear Cache and Rebuild Database" › Rebuild Database. It takes under a minute; launch Wolverine again.
Verify the game files if it still crashes on launch: check for a pending Wolverine patch (Insomniac is shipping crash fixes) and let it finish installing. A half-applied update looks exactly like a corrupted save — rule out the build before deleting anything.
Only if it still says the save is corrupted, delete the single corrupt save: Console Storage › Marvel's Wolverine › Delete, tick only the corrupt slot (leave others). You already have the cloud copy from step 1, so this is safe.
Restore your good save from the cloud: Saved Data (PS5) › Cloud Storage › Download to Console Storage › Marvel's Wolverine. If you use auto-sync, the newest cloud copy syncs on next launch — make sure that copy is your real last session, not the corrupt one.
If the crash persists after all of the above, rebuild once more after a full firmware update, and free up SSD space — a nearly full PS5 SSD can corrupt writes on save. Keep at least a few GB free.

Does cloud sync move it for you?

PS5 saves for Marvel's Wolverine live in Console Storage and only leave the console if you upload them to PlayStation Plus Cloud Storage (or copy to a USB drive via Copy to USB). A cloud-vs-console conflict resolved the wrong way — the older or half-written copy winning — is a common cause of a save that suddenly looks reverted or corrupt. When restoring, read the timestamps and pick your real last session. If auto-upload already pushed the corrupt save to the cloud, delete that cloud copy before it downloads back over a good one. No PS Plus? Copy the save to a USB drive from Console Storage before you touch anything — that USB copy is your only recovery.

Common mistakes

Deleting the save before backing it up. A PS5 save with no PS Plus cloud copy and no USB copy is NOT re-downloadable — once deleted it is gone. Upload or copy first (step 1).
Skipping the database rebuild. Most CE-34878-0 crashes on Wolverine are a corrupt PS5 database or cache, not the save itself — rebuilding fixes them without losing progress.
Blaming the save when it's the patch. Insomniac is actively patching launch crashes; a pending or half-installed update mimics a corrupt save. Update fully and verify before deleting.
Letting auto-sync overwrite your good cloud save with the corrupt one. If the console save is bad, turn the game off before it uploads, or delete the bad cloud copy first.

FAQ

Where are Marvel's Wolverine save files stored on PS5?

In Console Storage: Settings › Saved Data and Game/App Settings › Saved Data (PS5) › Console Storage › Marvel's Wolverine. They only leave the console if you upload to PlayStation Plus Cloud Storage or copy to a USB drive. Marvel's Wolverine is a PS5 title, so there is no PC/AppData folder.

How do I fix the CE-34878-0 crash in Marvel's Wolverine?

Most often it is the PS5 database, not your save. Back the save up to cloud first, then enter Safe Mode (hold power until the second beep) and run Clear Cache and Rebuild Database. Also install any pending Wolverine patch and free up SSD space. Delete the save only as a last resort, after you have a cloud or USB copy.

Can I recover a corrupted Marvel's Wolverine save?

Yes if you backed it up. Restore from PlayStation Plus Cloud Storage (Cloud Storage › Download to Console Storage) or from a USB copy. If you never uploaded to cloud and deleted the only console copy, PS5 saves cannot be re-downloaded — which is why backing up before deleting is the whole game.

Will rebuilding the PS5 database delete my Wolverine save?

No. Rebuild Database in Safe Mode re-indexes the drive and clears the cache; it does not delete saved data, games, or accounts. It is safe and is the first thing to try for CE-34878-0 crashes. Back up to cloud anyway, as a habit.
