How to Fix Epic Games Launcher Error Code LS-0018 [Solved]

by

Epic Games Launcher Error Code LS-0018 occurs when a game process is already running in your background operating system task logs. This execution freeze completely blocks the desktop client software from launching a fresh instance of the application, trapping your launcher button on a permanent “Running” state while nothing appears on your monitor screen.

Whether this application deadlock stems from an incomplete closing sequence during your previous gaming session or conflicting real-time overlay configurations, you can clear it. Follow this step-by-step troubleshooting guide to bypass error LS-0018 and launch your games instantly.

Common Causes of Error Code LS-0018

• Lingering Background Game Processes: Hidden execution files remaining active in your system memory after you close a game.
• Glitched Third-Party Overlay Modules: Discord or graphics software overlays trapping the application during shutdown paths.
• Mismatched Client Communication Logs: The primary launcher engine failing to register that a game has terminated successfully.

Method 1: Force Terminate All Active Game Processes via Task Manager

If your game fails to close out its system files properly, the operating system will block any new activation requests. Killing the old hidden process clears the background memory layout instantly.

  1. Press the shortcut keys Ctrl + Shift + Esc on your keyboard simultaneously to open your master Task Manager window layout.
  2. Ensure you are looking at the Processes tab layout screen and scan the list for the specific game that is refusing to launch.
  3. Right-click on the game’s background process name (such as Fortnite.exe or RocketLeague.exe) from the application grid.
  4. Select End Task from the context choices menu to purge the frozen program memory blocks from your computer.
  5. Close the Task Manager window completely, return to your desktop Epic Games Launcher shortcut, and click Launch.

Method 2: Purge the Epic Games Launcher AppData Configuration Repository

Accumulated temporary data remnants inside your system application data folders can easily warp launcher tracking files. Clearing this specific folder layout forces the client to build uncorrupted session states from scratch.

  1. Completely exit the application launcher by right-clicking the Epic Games icon in your taskbar system tray and choosing Exit.
  2. Press the Windows Key + R on your keyboard simultaneously to launch the manual system Run dialogue box interface layout.
  3. Type %localappdata% into the blank text space and click OK to load your user profile’s hidden application directory tree.
  4. Open the EpicGamesLauncher folder icon, double-click into the Saved folder, and locate the webcache folder.
  5. Right-click on the webcache folder layout and select Delete to sweep the broken temporary assets from your storage.
