My sims take an hour to chat with strangers

Almost every time I try to communicate with unknown sims (but this can happen with sims in my household too) they will take a long time to have a first contact then (in some cases the interactions are complicated even after the first meeting). Either they will try to look for a place to sit but they walk strangely, slowly, back up, stop then start again (this only for discussions with unknown sims). So my game runs very well (with the usual bugs of the sims) and it is only the sim with the one I try to communicate and mine that bugs, the sims around have no problem.

I want to point out that this bug has been present for a very long time and that I'm reporting it because bug fixes are in progress.

I'm playing on a MacBook Air M4 (I've never had a game run this smoothly since then, but the bugs are still present).
I'm playing with MCCC and UI cheats as mods, but the bug is still present when I remove the mods.

Sincerely, I hope my contribution will be taken into account. Have a nice day.
