Idk if you’d consider it a “hobby” (even though I’d say that has more consumerist connotations), but I’d strongly suggest finding a creative outlet. Personally I believe that there’s no such thing as an “uncreative” person, it’s just that most people never get the opportunity to learn a creatively rewarding skill well (and even when they do, many are left with no time/energy after work). It’s a catch-22. Still, unless you want to keep being a cog in the machine you gotta sacrifice something.
Also, art (in a general sense) is a lot better with human contact, idk what you’re talking about that is “doesn’t work”. You gotta find like-minded people. Sometimes you’re lucky and meet like-minded people by happenstance, sometimes you gotta go out of your way to find them (even if by saying it like that I still feel like I’m underplaying how hard that can be).
A final but perhaps more important suggestion is, learn about something. Instead of binging another tv show every week, mix it up with some educational internet browsing, or books, or perhaps you enjoy videoessays more. Again, an environment where you can meet people is better, but higher education has also turned into a human grinder that spits out ready-made workers for the machine so I can’t sincerely recommend it. But it could still be worth considering (depending on where you are… definitely not worth a 100k debt).
TL:DR find ways of satisfying your inner curiosity and creativity.
