Potty training toddlers drops from queue when initiated by caregiver

I've been having an issue for a while where if my sims (an adult or toddler) try to initiate the potty training action they'll go into a quick t-pose reset and cancel the action from the queue. All animations are typically able to be carried out (sometimes during the talking portion before potty training the toddler and caregiver will stare into space until the action is cancelled), but it's always right before using the toilet that the reset happens. The issue is reported as a constraint issue which could be due to the amount of objects on my lot in my main save file, but the same thing happens in a new save in an unfurnished house. I get this error following a couple of other actions as well, but the potty training one is the only error that happens consistently. I've cleared out any broken or outdated mods I've seen from BE and MCCC reports, but the issue still persists unless I play a reset game with no mods or save files. I don't want to have to build my save completely over again, especially since I've used MCCC to expand the size of my househould and wouldn't be able to save them to gallery for a new save.
