So 8.0.2 brought in new scene with Blair and Yona. Lewdness tracker and system and some general housekeeping.
I booted up your latest save file and had a Yona quest appear for me after interacting with her, and saw a Lyriel quest in ignored.
Other than that, I'm honestly not sure why you're experiencing this, but hopefully the save above helps with getting the ball rolling from here onwards.
