I want to launch up Unreal Editor but a message kept showing up, Serialization Error : Action Needed Corrupt data found, please verify your installation. It’s most likely due to clicking launch two times and repeatedly trying to press quit while loading, so can you fix this problem so I could launch it again.

Try going to your library, right click the engine version and select verify.

HI 100dollargamez,

Tactical_Beard is correct. If you go to your Launcher>Library>Dropdown engine menu>Verify it will check your engine for missing/damaged files and repair/replace them as necessary.
