stuck at 1700, help!!!

As per the note, I'm looking for someone to potentially analyze my games (either here, or privately) and advise (i) what are the lion's share of my weaknesses, and (ii) help me develop a pathway forward, ie, books study plan etc.  I currently study roughly 3.5 hours a day, broken down as follows:  45 minutes opening theory, 45 minutes book study (endgames at the moment), 1 hour tactics, 1 hour play.  I'm stuck and I'm really not sure why.  I'd love to breakthrough to the 2000 range if possible.  Any guidance would be deeply appreciated.  I'm open to a coach, and I've had a great coach before, but since I do so much private study, I'm not sure if that's the best pathway forward.

You have been playing here for more than 10 years.

How long have you been following your study plan? What books/lessons have you studied fairly recently? Have you done online lessons here/ elsewhere?

Have you ever had a diamond membership and run Insights? It could tell you if you are missing mates in 1 or forks or pins.

Thanks for the thoughts justbefair. In answer to your questions: In last 12 months or so, couple books on the psychology of chess, Nunn's book on strategy. Hellsten on opening study. Sierawan's endgame book. I did lessons with a coach for about a year. He was great and helped me advance, but I feel that I never really pinpointed my weaknesses. By way of a totally unrelated example, i used to play competitive squash, where my coach clearly pointed out what I needed to work on, so a i had a very clear pathway forward.
