If you use a supply pack instead of individual food items before long rest it should let you save without crashing. Atleast thats what worked for me.
It worked for me, too, thank you! This is a really weird, but interesting bug.
Other than that, patch 8 improved my gaming experience a lot, the game runs so much smoother now for me (I am playing on a gaming laptop, but it is already a view years old).
