Game Crashing--will not open Fortnite

I’m having trouble with Fortnite.
I recently made an account and downloaded Unreal Engine, updated it and even ran the repair option. The Epic Games launcher will load but after I enter my username and password there is a crash and a screen pops up that says that Unreal Engine has crashed and will not specify why.

I’ve tried different things, used YouTube fixes, internet fixes and I am getting nowhere.
Please help.
