Hitting uninstall throws the error below:
MusicBee v3.5.8447.35892P (Win10.0), 4 May 2023 21:19:

However, it does change the status of the plugin to "disabled".
From there, adding the plugin (to update it) prompts the error shown in my previous post.
Anyway, I just re-enabled whatever version was already installed (built in?). I just find weird that there was no .dll of that version in MB's Plugins folder.
But then again, I'm a newbie and I don't know what I'm doing

Can LyricsReloaded process synchronised lyrics or is it "only" about fetching static text from different sources?
On that topic, can anyone recommend sources for synced lyrics?
It seems MiniLyrics is a thing of the past now (?) and I can't recall the plugin I was using in Foobar for that back in the days.
