Screenshot of empty artist category with the tracks category not having covers or duration

SUMMARY
Elisa seems to not recognize music tags - whether they are in ID3v1.1 or ID3v2.3.0 or Ape format - and because of that, the music collection can only be browsed and played from the Tracks category. There, it contains all tracks with none of the tags that helps distinguish them: No artist name, album name, or music covers are shown. See the screenshot attached.
This happened after I upgraded to the Plasma and Frameworks 6 and Gear 24.02. Terminal output when launching Elisa from the terminal is pasted in the additional information, though I can't discern whether the information is useful or relevant.


STEPS TO REPRODUCE
1. Open Elisa v24.02, and search for your music. If needed, give it the path to your collection from the configure Elisa option in the menu.
2. Go to Tracks and Albums and Artist categories from the sidebar
3. You'll find the Albums and Artist categories are empty, while tracks are shown with no tags or covers in the Tracks category. Reset database and scan again or relaunching Elisa won't change this.

OBSERVED RESULT
Elisa fails to display anything in the Artist and Album categories (as well as Genres) because it seems to not recognize music files tags. Music collection can only be played from the tracks panel, which is a jumble of all tracks with no covers or even track duration.

EXPECTED RESULT
Elisa should be able to recognize music files tags and categorize the music collection based on them, so a specific track could be accessed from: Artist category in the sidebar, under its artist; or Albums category in the sidebar under the album in which it was released (according to its embedded tags), and so forth for the Genres.

ADDITIONAL INFORMATION
