My engagement dropped fast and hard

I don't know if this is related to instagram latest changes but my engagement has dropped severely.

My account is professional, so I was never able to use hard settings when botting and it's quite small (13k). But I used to have around 700 - 1000 likes on my pictures and now my latest post has 172 likes.

I've seen my engagement drop in the past but this is just too much. Any tips?
