But I’m possibly on a newer build than what you are running.
What happens when you delete that one and then add the defaults back (blue circle arrow)?

An empty document doesn’t contain any hatch patterns. You always need to first either create one in Rhino or go to the Document Properties and open the Hatch page. That will instantly create the patterns. Hatches have always worked like this in Rhino.
I thought that was the issue that you were running into with your workflow and when I tested that, I first did create a Rhino hatch object. But, for some reason that I hope the developers can answer, that didn’t make a difference.
