This is a rare error that occurs for some users. Nothing I can really do, as it's a problem with Unreal Engine 4 and not the game. :/ Sorry man, I really wish I could help. I have looked up some solutions to this problem but the only thing that came up was that if you're using a laptop to disconnect the charger or was it connect the charger, I don't know, one of the two and apparently that fixes the problem. Dunno if it'll actually work but it's worth a try if you're using a laptop.
