Game freezes - Year 2 Blue Casket

[RaemNL]

I'm at the point in year 2 where you have to go to the back of the blue casket. But everytime I try to go there the game freezes.

I'm playing the game on my Vita. I tried reloading a savefile from the start of year 2, played until I got to the point where I could enter the Blue Casket, but had the same problem.
Installed the game on my PS4 and downloaded the cross save file, but the game keeps crashing everytime I try to load the savefile.

Anything else I could try or do I need to restart the whole game?
