As title says. Her quest is auto failing with "Parvati was killed." whenever I pick it up, but obviously that isn't the case because I'm speaking with her, and playing on Hard difficulty, where companions don't permanently die as far as I'm aware. I started on normal but changed to hard part way through my play through so I don't know if that triggered it. I'm playing on the game pass version on a regular Xbox One.
I also settled things on Monarch storywise just before picking up her quest if that's any information you need.
