i have a few different thoughts about what you wrote
firstly—it can be difficult to get everyone on the same page, when they are all working remotely. for that reason, remote work companies are often using Slack and Zoom. there is a certain enforcement pattern to these tools, so that people are made to be communicating and cooperating. it can be made to be a fun thing too. like 2 or 3x a week...1st meeting is the agenda, goals, and thoughts/Q&R. second meeting is shorter and a bit more fun (perhaps people can post ideas for what it will be next week), third meeting is a wrap up + discussion
people get comfortable; it is what it is. on a practical level, especially with "intellectual" types, there is often going to be some friction around the socializing. but unfortunately, when you are in a group of people working toward something, having a bunch of atomic units acting independently is going to be counterproductive. on a deeper level, it is perhaps even harmful to those engaging in avoidant behavior
there is also a sort of problem with "intellectuals" in general. people on the higher end of the reasoning spectrum can become some of the most obtuse and conceited people, because they become used to being the smartest person in most rooms. the other day i was in a call with some folks talking about how we budget out tokens with some different AI models, and this dude came in and right off the rip tried to be demeaning, "oh, there are just deeper things to talk about than which model". it was like yes...it's not a deep topic, we are talking about something practical to us, and having a laugh. and he just kept trying to hijack things, turn it into his moment as the library of alexandria in his gay ass head, because models are just so uninteresting! people become rigid and egotistic
so there is perhaps hope that if it is possible to use more socializing tools for the offline work, things can get turned around. and it can be made fun! doesn't have to be a chore
but the way you write, also sounds like someone who has effectively been "boxed into" something, and your vitals are apparently reflecting it. i would say there is open-source work, as well as professional programming work, which is probably adjacent to what you are doing. your background lends itself to a lot of opportunities in different fields. if anything, take a break
