[2022] Bug Hidden Ones mission

Hi,
I'm at the very end of the game, i've done all of the quests and the Hidden Ones mission is my very last. I found all of the missing codex pages and gave them to Hytham. I had to talk to Reda next and to read the page from Bayek close to his settlement, but once I press Δ to read, the game does consider it but nothing happens. As if a cinematic was supposed to start but never does. I can speak to Hytham or Reda but there's no lines concerning the mission. And if I try to read the note again, nothing happens.

I briefly searched for an answer here, but everyone was only missing pages when I have all of them, since I gave them to Hytham. What should I do?

Thanks for the reponses.
