Somewhat frustrating, but I'm at the 'end' of my honour mode run (playing on xbox series X) and have just hit the end of chapter 5, on the lady vengeance where your companions leave you just before the boat crashes in Arx.

Suddenly, i cannot talk to anyone, use any items, interact with anything or do anything! My only save (honour mode) is on the ship so i cannot even load a previous save. Has anyone ran in to / resolved this issue before? I really don't want to lose 50 hour of progress.
