Assistance Needed with Bugged Quest in PoE2

Hello!

I hope you're doing well. I’m reaching out for help with a bugged quest involving Delvin in Pillars of Eternity II. After defeating the spirit, I’m supposed to speak with him to complete the quest, but the dialogue won’t progress, and the quest remains unresolved. Could you please advise on how to fix this?

Thank you in advance for your support!

P.S. i am from Russia, sorry for my english)
