Game crashed. Varloch spawned outside boss room on reload. Now I'm struck in Courtyard

The moment I killed Avelyne my game freeze locked, which btw is an issue on it's own, like every 30 min wtf. I closed force closed the game, reloaded and then Varloch was outside the boss room. I've tried portal to a friend, wall clipping, and relauncing but can't get out
