A lot of men were never taught to do this. We raise young girls to be incredibly social, but boys are not socialized to nearly the same extent. You can see this in Autism diagnoses. Girls are diagnosed as a much lower rate and the ones that do receive the diagnosis tend to be really severe cases. The leading theory as to why is that society places so many social expectations on girls that the more mild cases quickly learn to mask and pass themselves off as neurotypical.

Hell, I’m 35 and I just started a group chat with some of my bros in order to help with motivation to get things done (it’s basically a stand up meeting but for our personal lives/goals). NONE of them even know each other, they were just doing this to help me out because I’m burned out. 2 weeks in and they had all thanked me privately for giving them a social outlet and improving their mood. None of us usually text people unless we need to, and now we’ll routinely get roped into conversations because someone shares an interesting update.

Meanwhile my wife is juggling 3 different group chats in addition to half a dozen friends she keeps in touch with 1-1.

There might be some biological mechanism too, but I think a lot of it boils down to boys have “productive labor” modelled for them as ideal behavior while girls are taught how to be considerate friends.
