Help… Forbidden legend

Hello guys. Looking for possible advice/help. Currently doing the Forbidden legend quest line and I’m at Gauldurs tomb and on the “Reforge the Gauldur amulet” part of the quest…

I placed all 3 amulets on the pedestals, I then, fight all 3 sons and then after dealing with the final son… nothing. He just stands there. Not doing anything. My compass says he’s an enemy but I can’t touch him or harm him… he’s just standing there… the gates closed behind me so I can’t leave and I have no idea what to do or get him moving. I tried dragon shouting and magic to no avail…. Could this be a bug?

I want to reload back but honestly I had this same quest a month prior. Same issue, loaded back and forgot about it until I’m now trying again.

Help?…

Oh and I’m playing on a PS5..
