Tutorials/Help in Unreal Engine

So i was thinking, about the issues i've had when rebuilding lighting with swarm agent i talked about a while ago, should i try removing UE & manually deleting Swarm Agent, then reinstall Unreal Engine? Would that be a viable option to fix it?

So does anyone know how to fix this ghosting issue in the Volumetric Fog while keeping it optimized for VR? or do I just need to fake the volumetric lighting somehow. Help would be appreciated.

I need help! For the past few months I could never build lights, it instantly fails no matter what level, project, quality, or engine version it is, here are the Swarm Agent logs after attempting to build lighting as well as the error logs in the engine.
