Unfortunately it's not something I can update since it's a problem with certain PCs unable to run UE4 games. As for a tutorial, I don't quite know how to fix it myself, I just usually link a reddit post where someone asked the question and someone posted the answer though I believe you already found that and it didn't work for ya. Again, I'm really sorry I can't help ya here, it's like what I said, certain PCs run into issues like this with Unreal Engine games. D:
