Record whether Lost Ark closes, freezes, shows an Easy Anti-Cheat error, or restarts Windows. Check current Lost Ark notices, update Windows and the graphics driver, verify the Steam files, then follow the Easy Anti-Cheat steps only when the error names EAC.
Note whether the game closes to Steam, stops responding with a visible window, displays an EAC message, or causes Windows to restart. Record the time and any error text because each symptom may have a different cause.

Check current Lost Ark crash notices
Review Lost Ark's current Game Crashes and Errors section for a matching incident or named error before altering local files. Follow a matching current notice when one exists.
Open the current Steam listing and compare Windows, memory, graphics, DirectX, and storage with the PC. Install offered Windows updates and a graphics driver only from Windows Update or the hardware manufacturer's official website.
4
Restart and test once
Close Lost Ark and Steam, restart Windows, reopen Steam, and test once without starting unrelated overlays or monitoring tools. Keep Windows security and anti-cheat protections enabled.
5
Verify Lost Ark game files
In Steam Library, open Lost Ark Properties, choose Installed Files, and select Verify integrity of game files. Wait for the check and any reacquisition to finish before relaunching.
If the error specifically names Easy Anti-Cheat, follow Lost Ark's current EAC troubleshooting. Update Windows, close recognised conflicting software for one test, and copy the exact EAC message; do not bypass or remove anti-cheat.
Return to the same character, area, or action that triggered the crash. If it repeats, report the symptom, timestamp, PC specifications, driver source, verification result, and EAC result when applicable to Lost Ark Support.

If it does not work
If Windows restarts or shows a stop error, treat that as a Windows or hardware stability problem and write down the error details. Do not keep launching Lost Ark until you have checked the cause.
If only one character or area triggers the freeze, include that exact character, server, and location in the support report instead of deleting configuration or reinstalling the entire game first.
