They still appear in the mod menu when you start the game, but they just don't work in game. Why would this happen after just a normal, mandatory update?
Unfortunately, it's just a thing that some mods break after every patch. Slider mods, skin details, some alpha hairs, etc. were hit hard by this particular patch because they're somehow conflicting with things that they added for werewolves. This is, alas, normal and the price we pay for using mods and CC.
Watch your favorite creators' patreons, web sites, twitters, discords, etc., for updates and cross your fingers.
