Help with understanding this error in a Unreal Engine 4 game known as Absolver[4-20]

For some time now I’ve been getting this error when i attempt to boot up the game “Absolver” created from the Unreal 4 engine. Unfortunately, doing all of the suggested fixes such as upgrading my graphics card have turned up empty. Can someone here who is familiar with unreal engine explain to me just what this error is, and any fixes for my specific error? [4-20]

This forum is for Unreal Engine specifically, if you’re having an issue with a game even if it’s made with Unreal Engine you should contact support from the developer instead.
