Iray preview problem caused by an element of the scene

I've had a problem with Iray preview.: the preview wasn't appearing, regardles how long I waited, the image was staying grey, as it does when you start the preview. I assumed that it was caused by my computer being unable to handle the scene, or/and by the emissive lights I had just added. But searching for mentions of a similar issue on this forum, I noticed that a couple of people had mentioned that deleting a specific item in the setting had solved the issue. One had to delete a shirt, another a figure. I tried to delete every element one by one except a chair, and the issue indeed turned out to be caused for some reason by a specific item in the scene, in my case genitals. As it wasn't my lucky day, this was the very last item among many that I tried to remove. In fact, deleting the element wasn't necessary. Simply hiding it was enough for Iray preview to work again.

There's no real question here, but I thought that people might be interested to know in case they would face the same issue (I wasted a lot of time trying to get the Iray preview to work). Especially since I found the solution myself by searching this forum (the two posts mentioning the problem didn't have any answer, IIRC).
