Oh I have that same problem! I have no idea how to fix it exactly but I read another forum that said the game needs updating (1.69.59.1020) and to update any mods (which you said you did) if that doesn’t work and you are still getting the exception then the person said this “ One or more of your sims might have a stuck cc trait from before patching game and updating mods.
Move all your mods to your desktop in a temp folder except for the resource.cfg file.
Delete your localthumbcache
Load game but only to the map screen then 'save as' testing' or whatever then exit game.
(This will be the game save you load next time). Delete the localthumbcache again.
Move mods back into game and retest normally. If you still get same errors it's likely you still have a mod or some cc traits that are broken.” I really hope this helps! Or if you find a better solution then that would help me lol, I have not tried doing ^that yet so be careful!
