I can't open Epic Games Launcher

I can’t open Epic Games Launcher
I’ve just installed the EGL, but it wouldn’t open. There’s no error message, the icon is in my desk, it just shows the “loading” symbol and then disappears.
I can’t even play my game, I tried to delete and re-install multiple times, but it doesn’t work.
I’ve got a Windows PC, and everything is ok with it because I’ve installed other games and it does work.
Could you help me, please?
Thank you.
