Game soft locked after benedictus the first Herald

Hi

I have a softlock on my game, it happened near the end of act 4 after i defeated benedictus

A double kill happened (I died at the same time as he did) , i didn't want to fight him again so i let the cutscene play to get the quest progression

Saw the boss drop his loot on the ground and i pressed "Resurrect at last checkpoint"

Now when i walk into the arena, the boss start his death cutscene, and dispawn a few second later and nothing happen

The door to the forge is closed and i can't continue

Tried to close the game and reload it , but same stuff happen
