Troubleshoot LS-0013 in Epic Games Launcher
What to do first
Record LS-0013, verify the affected product and environment, correct the confirmed prerequisite, and retry once under the same conditions.
This is a general troubleshooting guide, not an announcement of a current outage.
Affected products and symptoms
- Product
- Epic Games Launcher
- Versions and conditions
- Windows / macOS
- Error codes and identifiers
- LS-0013
Symptoms
- The operation fails with LS-0013.
- The same failure is reproducible in Epic Games Launcher.
Causes and conditions
The official article identifies a product, compatibility, storage, update, network, file, or configuration condition that must be resolved before retrying.
Before you start
- Exit the game and launcher normally; record the account, title, complete error, and occurrence time.
- Before changing local saves or settings, find the developer-documented save location and copy it to another folder.
Precautions
- Launching through a sync warning or conflict can overwrite newer progress with an older save.
- Do not bulk-delete the game, userdata, or save folders without a backup.
Step-by-step instructions
In Epic Library select the game's menu > Manage > Verify and wait for completion; remove mods from the test state.
If only the game EXE is forced to run as administrator, open Properties > Compatibility and clear that setting so Launcher and game use compatible privilege levels.
Fully exit Launcher from the notification area, then remove only Epic's documented webcache folders and restart it. Do not delete saves or installed games.
Update Windows and close overlays or startup tools one at a time. If only one title fails, inspect its prerequisites and logs.
Check the result
- LS-0013 no longer appears and the operation completes.
- The selected version and settings remain after restart.
- A second test shows no new display, input, save, or synchronization problem.
If the problem continues
- Restore reversible settings from the notes and escalate without deleting user data.
- Prefer the PC maker or administrator procedure for OEM drivers and managed networks.
- Protect account names, tokens, and save contents before sharing logs.

Frequently asked questions
Will running Launcher as administrator always fix LS-0013?
No. Epic specifically calls out privilege mismatch; first review forced administrator settings on the game executable.
Does Verify delete saves?
It normally checks installation files, but review the game's save and mod locations before proceeding.
