I live in a city and this happened there too... maybe half of the kids in my son's class showed up a few times early on and disappeared entirely for the rest of the year. We had a few stops and starts ourselves. I don't want to be too presumptuous but this largely seems tied to family income. The families that could afford to have one parent working less often to help kids with school did so, everyone else disappeared. In one instance the only at-home help an 8 year old had to get Zoom set up was his 12 year old sister. We have programs for free laptops and free internet, but they rely on parents being savvy/available enough to see it through... so it's not unusual for those free services to go unused despite being needed.
