Can't view Duplicates in latest PMS 1.19.5.3006

[Volts]

In PMS 1.19.5.3006 I can’t view Duplicates in a library. The library view doesn’t load, and there’s almost nothing in the PMS logs. The “I’m thinking” spinner remains on the page until the “There was an unexpected error …” screen appears.

This happens in multiple libraries, big or small, and happens whether the library Does or Does Not contain duplicates.

If I roll back to 1.19.4.2935 or go sideways to 1.19.5.2916 it works fine.

Same problem over local IP web access, via app.plex.tv, or Plex.app.

Hardly anything in the logs when it doesn’t work. Just this Request, with no “Completed” buddy.

The other view I thought might be ‘special’, “Unmatched”, works fine.

Another post references this issue, PMS on Mac.

When trying to view duplicates: "There was an unexpected error loading this library"

Server Version#: 1.19.5.3006 Player Version#: 4.36.1 When I tried to view my movie library and selected View Duplicates, the display spins the progress wheel for quite awhile, and eventually displays “There was an unexpected error loading this library.” In addition, the display at the top disappeared, that allows you to select what you want to view. So I can’t switch to a different view. I’m not sure if viewing All would fix the issue, but I can’t get there so it’s a moot point. I have tried …

1.19.5.3006 may have been pulled. It’s no longer a suggested update, and isn’t on the download page. It also wasn’t mentioned in the announcement thread.

Ditto, when I selected Duplicates on a library, the CPU went to 100% and stayed there unless I rebooted the server. Plex would not stop normally or via kill on command line.
The server I haven’t used that view on yet, works fine with 1.19.5.3006
I’ve downgraded to 1.19.4.2935 and the CPU still jumps to 100% when trying to view duplicates.

Edit: fyi My downgrade was unsuccessful because I didn’t uninstall 3006 first. However, I don’t know how to uninstall without qnap also deleting metadata and preview thumbnails (2 million+ files) so I’ll just not view duplicates until a new version with the bug fix.

Same issue here. Cannot view duplicates and scanning is incredibly slow. Also pegging my CPU super HARD when I do anything. Running version 1.19.5.3006 on QNAP TVS-951X.
