Hi,
We unfortunately can't comment either way without you providing the error report/log. It should be in the game's main folder as a .txt. If there's none there, your crash was likely related to a system error and not the game itself.
You can check %appdata%/Roaming/Ren'Py and go to the SSWK folder there and see if there's a copy of the file called "persistent". If there is, you can copy it into your game folder's save folder and see if that works.
