actually, i believe this experience is more common for fathers at least than people want to admit. especially in western society fathers are generally expected to be more involved, and have a hard time when they come from a family where this wasn't the case (so they don't have a good role model) nor have a partner that encourages them to be involved, or worse a partner that actually discourages them.
i have been struggling with this too, especially because i had quite different expectations going in.
but the thing is that what gives you joy very much depends on your own expectations, and you can change those. i believe it's the same thing as with a job. there are people arguing that you should love your job, and if you don't you should not be doing it, while others claim that most people don't have a choice but to take a job that they don't enjoy.
I think it's ok if you don't find joy. Personally I had a very involved father and supportive partner. I understand my duty and am fulfilling it with full acceptance and gravity, I just keep this one piece of independence for my sanity-- the right to the validity of my emotion regarding how that duty makes me feel.
i do find joy, just not only in the way some people may expect it. (like i enjoy playing with the kids, but i don't enjoy not having much time to do so)
i think the primary problem is expectations of others. i may be lucky, that i do have a supportive family and partner that do not push any specific expectations on me, so i am free to find the enjoyment where i like. and a strong part of that for me is that i enjoy that i have been given this responsibility and am able to take care of my family to the best of my ability. in other words: i wanted this life and i am thankful to have gotten it, even if it turned out different than i thought it would be.
The main expectations I am driven by are to provide the child with adequate resources to thrive, to not neglect the child, and to give them a good footing to navigate this life. I'm not sure if these are expectations that can reasonably be relaxed, I'm just pretty much resigned I'm in for a long slog to provide these for the good of the child at great effort to myself whether it pleases me or not -- the circle of life I guess.
I see you, fellow dad. Thank you for having the courage to speak up and for fulfilling your duty as a parent, rain or shine. No judgement from me, only respect.

finding that joy may just take some searching.
