I would need to see your custom criteria file to say with any certainty, though crashing to desktop with no error is a new one on me. I haven't had any other reports of similar that I can recall.
What is a Taylor's Ring ?
I like this one. Might take a stab at it.
I'm not sure of your purpose here, but I add the Arrival Distance to the "Detail" section of all the criteria I write so I can see at a glance whether or not it's reasonable to check a thing out. 200k ls is way past my personal limit, but you could do the same to any criteria you end up using.

Yeah, it looks like a lost cause. The last post in that thread concluded that a ring with very low density was visible because it had thick mist.
Belts are specifically filtered out of the default wide ring check. Pretty much every belt would trigger it.

Thinking more about how to distinguish actual ringed stars from those with belts, here are some journal entries of a selection of pertinent "rings:"

I tried adding a check for "ReserveLevel" greater than zero to the Offset Ring Orbit, but of course, that eliminated all the stars, which I don't want to do due to things like example #2. I discovered this because I also added the parent body type to the "Detail" section of the criteria, and only planets were listed. I removed the check, and found that stars leave the "Parent" field blank, so it just reads "Parent Distance xxxxxls," instead of "Parent [body type] Distance xxxxxxls. So that's a little helpful, at least, since you can then see if the bodies those moons orbit have wide rings:
13 g (highlighted) has an offset ring orbit of an unnamed body, thus its parent is a star. Body 13 (top) has a wide ring. Bingo. If body 13 had no wide ring, it probably wouldn't have one at all, but a belt. Which made me wonder if there are any stars with actual rings that aren't "wide" per Observatory. I'm pretty sure I've never come across any. Then I wondered how Observatory evaluates "Wide Rings," and what makes it detect stars that have them while not detecting stars with belts. Because I bet that would be the ticket to detecting actual ringed stars; if a body is a star, and does not have a wide ring, it does not have a ring, but a belt. Conversely, only stars with wide rings have rings at all.
