Having the exact same issue, seems to be only with one household. I’m trying to narrow it down and see if it’s one sim who is a teen vampire. I have no mods and never have
Can confirm, it’s only with the one sim. As soon as i click on her the game freezes for a minute and then her simology pannel is broken and i can’t open any other panels including the menu. It also then breaks the panels for other sims. Inviting her to another household and adding to family doesn’t fix this
