Error after beating first level

[m00c0w]

So after seeing that another achievement had been added, I decided to reinstall the game, though I found out I had lost all of my progression (probably due to uninstalling). Thus I played the first level, and after beating it, the game crashed and this error was shown:

Oops, that was a mistake. Sorted now, hopefully.
