Based on what you said, I tested my copy (0.47Final) by starting a new game and it started fine.It shouldn't matter I've played the last update and it worked fine then.
It's just starting new game always crashes it.
loading a save works, but starting a new day crashes it most of the time.
but it is odd that you can load a save file fine but can't start a new game.
As a test here's a "New Game" save I made
and just to see, can run this quick test,
and maybe sd729178 can try this
back up your saves, delete the save folder completely and try running a new game again
