It sounds like a paradox that there would be simultaneous epidemics of loneliness and and standoffishness but they cause each other. In one direction the cause is obvious, in the other lack of socialization causes people's "calibration" to go off as their learned tolerance to unexpected things fades. Real social interactions involve a lot of imperfection and what you sometimes see is that without being desensitized, lonely people's standards can be unreachable. (Other commenters have alluded to this being a result of hyper stimulation on TikTok but it predates it.)
