Quick answer: Restart the PS5 and install the latest system software. If CE-100008-9 appears only when launching one game or app, check its update, restore licenses, and then delete and reinstall that application. PlayStation’s code-specific guidance recommends restart, system update and reinstalling the affected app.
Before you start
- Identify whether the error affects one app or the whole console.
- Sync saved data where supported before deleting a game.
- Keep enough free storage for a fresh download.
- Do not delete saved data unless a separate official step requires it.
Fix CE-100008-9
- Restart the PS5. Use Power > Restart PS5 and test again.
- Update system software. Open Settings > System > System Software > System Software Update and Settings.
- Update the game or app. Highlight it on the home screen, press Options and choose Check for Update.
- Restore licenses. Go to Settings > Users and Accounts > Other > Restore Licenses. This does not delete games or saved data.
- Check storage. Free space on the installation drive and complete any paused downloads.
- Delete only the affected app. Highlight it, press Options and choose Delete. Keep saved data intact, restart, then download from Library or insert the disc again.
- Rebuild the database if several apps fail. Start Safe Mode and use Clear Cache and Rebuild Database before considering Reset PS5.
Why this works
PlayStation documents CE-100008-9 only as an application error. A restart clears the active session, system and app updates replace incompatible components, and a reinstall replaces damaged application files. Restoring licenses helps when the download is intact but ownership cannot be validated.
Alternatives
- Test another app to confirm the scope.
- If installed on M.2 storage, move or reinstall the app to console storage for one test.
- Check PlayStation status if license restoration or downloads fail.
- Contact the publisher if the error began immediately after a game update.
Warnings
Deleting an application is different from deleting saved data. Read each confirmation screen. Do not initialize or reset the console for a single broken game until official app-level steps fail.
