[ARCHIVED] Sim doesn't interact with others and instead starts dancing

Product: The Sims 4
Platform: Mac
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? Current/latest one
What expansions, game packs, and stuff packs do you have installed? Vintage Glamour Stuff, Vampires, Tiny Living, Spooky Stuff, Spa Day, Seasons, Realm of Magic, Parenthood, Outdoor Retreat, Laundry Day Stuff, Kids Room Stuff, Island Living, Holiday Celebration Pack, Growing Together, Get Together, Get To Work, Get Famous, Eco Lifestyle, Discover University, Cottage Living, Cool Kitchen Stuff, City Living, Cats & Dogs, Blooming Rooms Kit
Steps: How can we find the bug ourselves? Interacting with sims and most objects.
What happens when the bug occurs? When attempting to interact with another sim/NPC, my sim and that other sim disregard the interaction command and start dancing in place. Invisible actions fill up the queue bar. When interacting with certain objects (such as a sink or toilet), the sim will at times either start the animation in place (i.e. start brushing their teeth before having even reached the sink) or start the task (i.e. going to the toilet) and the invisible actions will queue up again and the animation will continue until the game is exited.
What do you expect to see? Sim starts and completes the action/task. Task bar does not queue with invisible tasks. When interacting with other sims, sim to complete that task/interaction instead of dancing and getting stuck in place.
Have you installed any customization with the game, e.g. Custom Content or Mods? Yes - not anymore, removed entire folder since recent patches. Removed localthumbcache as well.
Did this issue appear after a specific patch or change you made to your system? Yes, after first lovestruck base game update. Has continued through other patches since.

I have tried updating Mods, removing Mods, removing the entire Mods folder, repairing my game (twice) and nothing fixes the above. I have created several new games after following the remove Mods-remove cache-repair process and encounter the above bugs within seconds of entering a game making it unplayable.
