Robotic Arm Stuck

I’m playing on Xbox doing a no cheats run, and I just wanted to change my Sim’s outfit but the robot arm from the Discover University pack will not come off. I’ve tried editing in CAS, changing outfits, switching careers to trigger different work uniforms, putting on event costumes, travelling to different lots, and even turning the Sim into a vampire to see if it would reset anything. Nothing’s worked. I really don’t want to use cheats, has anyone found a fix for this?
