If there is a better place to post this, please let me know.

This is about the best place you can post that error message as a GOG user.

If the game keeps crashing from loading that particular save slot, my educated guess would be that the option Start again from the Prisoners' Cells would fix it.

Yeah, I started a new run with no problems. Seems like that specific crash is caused by the new item Tornado, as I've seen it discussed on reddit. No problems with it during the run, you just can't load a save with it equipped. Next run I finally beat 4-cell difficulty, so overall I'm happy.
