after 5 years abbot is still busy 😭

I started a new game about a week ago and today I reached Diamond City and suddenly I remembered Abbot and the painting, as I said, i haven't played for 5 years but i see that the problem remains, so anyone knows how do I make Abbot talk to me? I know it's not a big deal of a sidequest but i went to him with the hope that I could finally do it but it seems not 😭😭
