I personally started taking guitar classes after a long period of stopping and I must say I really enjoy it. First, because the lessons are really adapted to the level in which we restart, which is really what I needed. Second because from there we build up techniques/music knowledge, and feels amazing realisation to translate progression into mastering a song. Third, this motivates me to work personally on the items we see in class and to improve because, yes, I'm accountable for my own progression :) I can only recommend you to jump on this journey.
