How do I get rid of this ghosting caused by Lumen GI?

Yes, my target FPS is 60.

My workaround for now has been to have the indoor areas totally dark which is something I can do considering that the world is post-apocalyptic and there would be no electricity. When I remove the emissive lights the ghosting goes away.

The reason can be lumen screen traces, try typing

r.Lumen.ScreenProbeGather.ScreenTraces 0

in console. It will remove all screen space GI, but should remove ghosting too.

If you still need Screen Traces, you can increase Grid Resolution (default is 48). I didn’t test, but assume this will have performance impact.

r.Lumen.ScreenProbeGather.RadianceCache.GridResolution 256

I encoutered the same issue, no idea why either.
