@Xemisa2World I've just tested this on teens in my game (on Xbox Series X) and it's working for me.
Have you tested other skills with this teen? I'd also test other ways of learning Handiness and see if all methods are broken, so I'd try the woodworking table, using the Tinker interaction on plumbing and see if the same thing happens.
I would also test on a different teen too if you haven't already in a different household. I sometimes use a base game Sim to test, so maybe someone like Malcolm Landgrabb or Cassandra Goth (if still teens in your game) by switching to his household for a minute. If you can take an image too that's useful.
