somewhat similar bug with "Kyne's Sacred Trials" where I exited out of the dialogue with Froki at the "Tell me what to do"/"I'm not interested." or whatever part, but now that I want to do the quest, Froki has only the "I'm not interested" option for that, so I can't even start it. I really doubt it's related in any way to your issue, but it might be...
Maybe a previous save could help you somehow. If not, I don't know.
