i'll likely have to have caro intervene on the save file itself tomorrow, but i'll try loading it up too, add them to that onedrive, both one made as far as you can rollback in the previous version and the one you already had at the end.
A few things i can suggest now is to make sure you are using the latest versions, at least 0.30g for the newest one, and see if you saved during those few lines that ask you what difficulty you want to play on when you load a save where you hadn't chosen yet (since the difficulty choice got implemented recently)... it shouldn't be a problem tbh, my saves do work, but might as well check that.
I take it you tried to click "ignore" for both saves down there until it crashes completely? And that you have no saves at all before being caught.
