Supposedly large DOF

I have some number of photos for which I cannot find how to resolve issue of sharpness with my D3500.

The settings are 18mm, f/16. I focus on subject that is ca. 3 meters away.

According to tables, hyperfocal distance is about 1 m. So everything behind 3 meters should be in focus for sure. Yet some of my pics look as if they were taken with some truly large aperture.

The problem is that the main subject is decently sharp, but not the other distances. If there is large diffraction issue, or misfocus, or camera shake, the subject wouldn't be in focus. Yet it is, but the other parts of the image are not.
