Sims can't ride horses

Since the recent update my sims cannot ride their horses. They can mount them but as soon as their butt hits the saddle they glitch out and end up standing beside the horse.

I play vanilla so it's not mod related this time (fyi I read a thread from 2023 about this), anyway EA please fix ASAP. This game is no longer fun with the constant glitches we have to deal with.
