GAMEBRAKING: Stuck in Jedha as Cere. Darth Vader does not spawn.

So, yesterday I got to the cutscene where Vader shows up to fight Cere. As the cutscene ended, I left the game as it was getting late. Today I cannot continue the fight. DARTH VADER IS NOT HERE. I already tried to rest, go as far as the game lets me and comeback, exit the game and comeback. BD-1 is also glitched, he floats in the air above the arena.

pls help I don’t want to have to start a new journey.
