Hello, Angel.

Do you know what caused this crash? Is there something that happened to the engine the last time you used it, before you used it today?

You said that when you try launching 4.2, the launcher crashes. Do you have other versions you could try launching, like 4.1 or 4.3? If not, a reinstall may be your best option.

I have installed the 4.1 and 4.2 only with the last one i have the problem, the 4.1 works fine.

I would recommend deleting the engine and reinstalling it. It sounds like there is something wrong with your launcher, which means you can’t go to the Library to Verify your engine installs.
