i'm generally in the 'quit' camp.
i've been in this type of situation more than once -- i've job-hopped a lot, done a lot of contracts, etc. -- and i am _not_ in that situation right now. praise all that is holy.
i currently dislike my job, but it's more fit, product, and managers, etc. -- it is definitely _not_ because I don't get along with the various nice people I often interact with - who are really sources of joy every day (def not all of them). (i just watched some of a steve kerr interview on youtube and he talks a lot about warrior culture and gave this anecdote about Pop and his just wanting to have a good day, etc.)
that situation -- the one you are in, one that I have experienced multiple times -- is brutal.
my guess is that you could do a million things that might make it slightly less worse over the coming months and years, and you'll end up with a heart attack and depression and all sorts of other niceties.
sometimes a shit team/people/culture/company is just that -- and you _may_ need to get out.
main question i would have is, how do you avoid this happening at the next place? you probably would _not_ be that unlucky, but i'm sure it has happened to others.
i think i have actually landed in this situation after, during the interview process, people told me how _awesome_ everyone was, how awesome the company and culture and whatever was, and then you find out it's all rather shit. like some bad holacracy dream -- everyone acting happy, but is really ready to kill themselves.
some of them might actually have believed it -- and i have almost certainly sold prospects on the awesomeness of our company/team/culture when i knew better. why? i dunno. stupid/evil fucking human psychology prob. "Let's see if you can convert this stupid mf -- I'm not going to suffer alone -- we need bodies -- and he prob doesn't really care -- he's here b/c he needs a job, not a good or ideal job."
start interviewing, get out. you can keep an open mind about staying, maybe make an effort to break things open a bit, change things up, maybe like others have suggested - going to the office more, etc. but def start leaving.
also, i hear hybrid work can burn people out faster than full on-site or full remote. so, if you're not required to be there, don't be. or ask for a couple of full-remote weeks, then ask for one more, then give your notice.
