I don’t have any real advice for you except to say that you’re not alone and what you’re experiencing is shared by many. I’m turning 34 next week and feel similarly, despite having achieved a lot of “success” in my business life. I too haven’t had a relationship in many, many years and am disillusioned by technology. I miss my 20s and envy the younger generation for many things. My body is getting older and more tired too and my natural optimism is less present these days.
I think there is a natural change that happens around this age as the energy of youth starts to be tempered by the wisdom of age (not meaning to sound lofty, it’s just how it came to my mind). There is an opportunity to start seeking things of more meaning and purpose in life, whether it is through study, career change, creativity/hobbies, mindfulness or spirituality, time in nature, settling down, finding new friends or rekindling old ones, moving on, a different kind of travel, etc - it will be different for everyone. You may also be depressed or burned out, which is a whole other thing (that I could also heavily relate to). But I think it’s not correct for people to offer armchair diagnoses over the internet and you should find out what’s true for you.
People also seem to be recommending travel above all else, but this isn’t always a panacea and is not right for everybody. There can also be real value in staying put and changing on the inside, if that’s what’s true for you.
In fairness, OP asked for armchair diagnoses. It's hard to stay away from recommending travel or whatever works for you, but that shows that it's a question that a lot of us (a surprising number of us, from this thread) are struggling with, so everyone wants to test their own theory.

Good luck out there
