I have had some very quiet friends over the years. I liked them as people, so I would hang out with them, suggest we zoom, meet for coffee, etc. However, I clearly remember experiences with some of these people where I was forced to do almost all of the talking, just to keep the conversation going. And this often meant me just struggling to squeeze out anything I could think of about my life, my thoughts, my job, my relationship. I tried to engage them but often got just monosyllables. At the end, I often felt exploited, that they were just somehow eating up whatever I had to say but not revealing anything about themselves, almost like I was there to entertain them. It felt so one-sided that I dropped some of those friendships. I'm not saying that's what's going on with you and your contacts, but that was my honest experience of interacting with extremely quiet people. Not sure why they were like that. Sometimes I felt they had an issue with letting themselves be vulnerable, but for sure they were not meeting me halfway.
