UPDATED: Need help removing multi-line artifacts

I’m getting some weird line displays on ALL surfaces. They almost disappear when very close to the object but become more pronounced the further away.

PostProcessingVolume>Rendering Features>Ambient Occlusion>Radius> higher than 100, the effects gradually fades away but so does my “shadowy goodness”.

Any thoughts/help would be appreciated. See pics
