Unreal 4 Engine Crashes on Launch

Well I was just trying to play Fortnite with some friends and then this incident occured; honestly I’m extremely confused about what the issue might pertain to. If you want contact me and I’ll attempt to find better information about what could have possibly occured during this incident. I’m gonna attempt to shut down the entire Epic Games launcher and see if that might succesfully fix my current situation.

Here is the crash diagnostics that I found:
