Epic Games Launcher Crashes when started

When I click on the Epic Games icon it doesen´t open. It opens a black box that says: "An unreal process has crashed: UE4-EpicGamesLauncher.

I have Windows 10. Everything is updated. It opened a few hours ago but now it doesn’t.
When I go to screen adapters it only shows me the graphic card that I bought and not the internal one; so that isn´t the problem.
¿how do I fix it?
