Ghosting and Smearing in Renders all of a sudden. Please help.

I cannot figure out how to get rid of this ghosting issue. Everything was rendering perfectly, and then out of nowhere it started happening for small portions of the video render and now it’s constant. I have tried so many different things (all variations of AA, removing motion blur, playing with lights in my environment, blend modes, material issues, changing project settings, frame rates, etc) and researched it to no end, but NOTHING is resolving the issue. Any help is very much appreciated. Thank you!
