Plex not generating preview images?

Admittedly, this is a very minor issue. Starting today the images won’t generate for Extras or non-metadata videos. What changed? (And yes, I’ve already tried many of the “fixes” that have been discussed over the years).

And today it appears to be fixed. (Mostly)
