Additional information

I recently started populating my own music library on my NAS. I added 2 batches of songs around 30-50 songs per batch, all .flac. The first batch of songs I have no issues with playback in Symfonium directly playing on my S25 Ultra. I tried to add my 2nd batch of songs and all songs from this new batch has this error exclusively on Symfonium. If I play the same songs on Navidrome or Feishin the songs plays fine.

Symfonium Verion 14.1.0
Android Version 16
One UI Version 8.5
