The attached image is a crop from one that shows a strange 'ghosting', only at this area, as indicated. Whilst the image was one of which I had missed focus on the face, out of focus areas and those that show subject movement do not normally appear like this. The exception being those using fill flash where a double exposure is evident.
The subject was moving, running and had a bright background of sea and sky that was not overexposed. An image of another runner taken a few seconds before with their hand in a near identical position, same background, same settings does not show similar ghosting.
Equipment - Z6, 70-200mm @ 200mm, 1/1600s, f/3.5, ISO640, VR On.
Any clues?
It would be better to also see an attachment of the entire image to see where the focus fell and how sharp are those details. And possibly, to see other similar aberrations in the out of focus sections of the image.

This is the original uncropped with +0.5 exp in pp. Focus box is shown on the right ear in ViewNXi which means nothing at times.
It looks like a hand-arm movement artifact, to put it succinctly.
I would guess VR on ???? .Why VR at 1/1600 sec

Is the same thing as when a moving object is slanted in a photo, like when panning. Maybe the processor read/write speed is to slow with moving objects & why Nikon went to 2 processors in the II versions of the Z6 &7. One just for AF so one of the processors could work soley on processing the image, if I understand it correctly. Just a thought on the possibility.

Why pixel peep a trash bin photo?

I have not found that subject movement due a too slow shutter speed gives such distinct lines. It is normally just a smooth blur.

I've found VR assists with a steadier view in the viewfinder assisting placement of focus point. It can be detrimental if it has not been allowed to settle but with the Z it's on full time.

I have taken thousands of similar images with this combination and not seen this before other than when using fill flash with lower shutter speeds.

Not sure I would consider viewing such an easily seen anomaly in an uncropped image downsized to around 2048 px wide on a monitor as 'pixel peeping'. Regardless of any other obvious straight forward failing in the image.

Anyone arguing about shutterspeed and VR/IS don't know anything about circa 2023
modern camera equipment.

Hmmm... I don't have any Z camera, so my comment could be way off, but it looks like a dual exposure.
Something like shot - move - shoot.
Might the Z6 have such a capability ? And if so, could you check if it is enabled?

The Z has a 'multiple exposure' mode and it's certainly turned off.
But you've given me an idea for some experimentation with runners moving parallel to the sensor.
