[2022] Exclusive quest can’t save

I’ve had a look through known issues but can’t find anything obvious relating to bug... (AC Valhalla)

For past couple weeks when I load game up it’s titled as an “exclusive quest”. I can’t get out of it or load a different save. The game also isn’t auto saving, and I get “can’t save game right now” when I try manually. I hoped it would get patched in Ostara update but no joy so here I am. It’s super frustrating and I can’t progress at all; please lmk if you want screenshots or something.

(I’m on Xbox one s)

thanks
