Elden Ring 'Failed to Load Save Data' — How to Fix It

What it means

'Failed to load save data' (or 'The save data is corrupt and could not be loaded') means Elden Ring couldn't read your save file at startup — so your character looks gone.
The usual cause is the save file (ER0000.sl2 on PC) getting damaged by a crash or a forced shutdown mid-save, or a cloud-sync conflict where two versions of the file collided.
There's often a backup sitting right next to the broken file, so don't panic and don't start a new game yet.

Affected Models

Elden Ring on PC (Steam)
Elden Ring on PlayStation 5 and PlayStation 4
Elden Ring on Xbox Series X|S and Xbox One
Elden Ring: Shadow of the Erdtree

Common Causes

Save file corrupted by a game crash, BSOD, or pulling the power mid-save
Cloud sync clash — local and cloud saves out of step, then merged badly
Antivirus or a disk error damaging the save folder
Editing or moving the save file by hand
Running the game from a failing drive or a nearly-full disk
A mod that wrote to the save and left it in a state the base game can't read

How to Fix It

Don't start a new game — it can overwrite the backup.

Elden Ring keeps an automatic backup, but starting a fresh save can clobber it.
Close the game first and work from the file system (PC) or the console's save manager.
Restore the backup on PC.

Go to %APPDATA%\EldenRing\\ — you'll see ER0000.sl2 (the save) and ER0000.sl2.bak (the backup).
Copy the broken ER0000.sl2 somewhere safe, then rename ER0000.sl2.bak to ER0000.sl2.
Launch the game; it should load the backup.
Sort out cloud-sync conflicts.

In Steam, if it asks which save to keep, pick the one with your real progress.
If you're not sure, temporarily disable Steam Cloud for Elden Ring (Properties > General), get a working local save, then re-enable it.
On consoles, download the cloud save from the system's save-data menu and try that copy.
Verify game files.

PC (Steam): right-click Elden Ring > Properties > Installed Files > Verify integrity of game files.
This fixes a damaged install, though it won't repair the save itself — that's what the backup is for.
Check the drive.

If saves keep corrupting, the drive may be the problem.
On PC run a disk check (chkdsk) and make sure the drive isn't almost full.
Move the game to a healthy drive if errors persist — and from now on, exit to the main menu before closing the game so the save finishes writing.

Frequently Asked Questions

Is my Elden Ring character gone for good?

Usually not.
The game keeps a .bak backup right alongside the save on PC, and consoles keep cloud-save history — restoring one of those normally brings your character back, at most losing whatever you did since the last clean save.
The character is only truly lost if both the save and the backup are damaged and there's no cloud copy, which is rare unless the drive is failing.
