Unable to learn "Song of Trixion" disapeared from my inventory ! Can't go through the main quest I am blocked

As I said, I was doing the quest “To the edge of the World”

At a certain point you get a book that ables you to learn “Song of Trixion”,

But as soon as I tried to open it, the item disapeared from my inventory.

So now I am blocked, I can’t do the main quest since I can’t play this song for the said quest.

I am on server Calvasus

Please someone help me !!

I see three options.
#1. Relaunch the game
#2. Contact support via a ticket.
#3. Replay the story with another toon on the same server. (dont know if this will work. Going off of other songs being server wide.)
