[2022] Population issues with Humans (won’t reproduce despite having room)

So basically in my settlements until now I’ve been managing to reach some 27-30 ish amount of settlers and, despite making sure to build nice 3x3 two bed houses for everyone, after a certain point they just stop reproducing and the population just ages away or I forget to auto plant the crops and the village falls into some Malthusian collapse.

Is there something wrong in the way I’m building the dwellings ? Normally when I check the buildings settings the houses seem decently occupated with 1 settler or 2 per home. I even make sure sometimes to cancel all jobs and let them have free time but still no bebes.
