Album artist variables not being generated [AAV 1.0, Picard 2.12.3, Windows 11]

[ghost]

Been seeing weird behaviour in my file naming scripts that seems to be chalked down to artist variables not being generated. I was able to verify by using the Show script variables plugin, which shows all variables including hidden variables and those generated by plugins.

(The artist_mbid... plugins are from AAD, which I've disabled. Issue still persists.)

As shown, the track variables are being generated but not the album ones.

Going into the Error Log, I find this:

E: 14:00:27,707 ui/item.error_append:108: <Album 3ac55d04-cb97-4e04-9e80-7639b102c728 ''>: Traceback (most recent call last):

It sounds like something is removing the original album metadata before the plugin is run. Can you please try disabling all plugins except for "Addtional Artists Variables" and see if the problem still exists?

Also, can you please provide me with the MBID (or link) to the album that you are loading that doesn't work? I haven't been able to reproduce the error here with any albums that I've tried.

Sorry for the late response, the album I tried was: https://musicbrainz.org/release-group/efb9bb1e-adc9-492f-b644-bee3701d5cd6

I did try this recently with some of the plugins disabled (Additional Artist Details, Deezer cover art, Feat. Artist in Titles, Standardise Feat.) and it seems to work now (tested on Taylor Swift - The Tortured Poets Department and Talvekoidik - Spitzbergen). I'll see which plugin is causing it soon.
