The LRC are found your issue is something else.
You should not be able to reach that screen if there’s no lyrics found, so how did you get to this? Already opened from another song or the button was there and the lyrics are not parsed correctly.
Did you stop playback after the sync and restart one, Symfonium cache things, so it’s possible it shows the cache without the lyrics.
Just in case can you upload that lrc file to https://upload.symfonium.app so I can check if it’s parsed correctly ?
