I'm playing Far Cry 6 presently and it was interesting to find Skyrim-esque bugs like NPCs running over each other, or ending of a quest being a chaotic mess. It made me realise that most open world games inevitably become buggy when multiple systems within a game interact with each other. I had similar experience with Horizon Forbidden West. Not saying Bethesda games have same level or severity of bugs as these, but the class of bugs (NPCs glitching out, random world events colliding with each other, everyone speaking all at once, uneven geometry at places, armour clipping) are similar across open world games despite coming from different engines.
