How to Stop Unreal from Running

My Fortnite keeps freezing and crashing during games, and I realized that the pop-up that shows up is an Unreal Error. I was trying to figure out if we don’t need Unreal for Fortnite, how do I uninstall/deactivate Unreal. I tried uninstalling it from the Control Panel, but the app didn’t show up.

I suppose you do understand that Fortnite is written by Epic Games in Unreal Engine. Without seeing the pop up that you are talking about, I assume that it’s some type of exception/crash report that automatically gets created when Fortnite crashes. I am also assuming you haven’t installed UE4 on your computer, otherwise you most probably wouldn’t be asking.
