Crashes on launch

Fortnite was working completely fine for me for most of the time I’ve had it but a few days ago when I launch it(fortnite) it crashes. As soon as it crashes the Unreal Engine 4 Crash reporter pops up. I have searched for quite awhile and i have tried running in compatibility mode, verifying, and reinstalling it. I do not know what is causing this or how to fix, any info would help :D. Thank you .

Every time I launch the game, it will become a file where it says something that the game will fall. it annoys me a lot!
