First issue is your folder organization.
You are missing a superfolder for the AlbumArtist. (which in the case of a sampler is Various Artists)
/Music
/Various Artists <-- "AlbumArtist" superfolder
/Permanent Vacation 8 (2023)
01 - Wallace - Largo.mp3
02 - Artist 2 - track 2.mp3
...
Inside of an AlbumArtist superfolder, there must be not a single track which has a different AlbumArtist tagged.
Otherwise all hell is breaking loose – particularly if you enable “prefer local metadata”.
An example of a whole album:
Notice the folder structure and the embedded metadata, the AlbumArtist in particular.
Don’t forget to tag the track numbers as well!
