Good catch! I didn’t think of that one…
No typo’s that I can see… So indeed perhaps Plex is just not happy about that particular movie, and maybe the Plex Dance will sort it.
Also, to rule out a problem with that particular movie, you could try just temporarily adding an extra to any other movie to see what that does.
I often use a tiny little video file, call it Other.mkv, and place that in a sub-folder under the chosen movie called Other.
So you end up with…
Movies\My Movie (2019)\Other\Other.mkv
