can't click on sims or objects

so i've had this problem since a few updates ago, but i can't click on any of my sims in game or CAS, and i can't click on any objects in game or in build/buy. i can click on the ui, and any icons. like if i click on the hunger need, my sim will go eat something, and i can edit traits and stuff in CAS but that's it. my game and mods are up to date but i've got the same problem with my mods removed so i just don't know what to do anymore.
