This bug crashes the game when you click "New Game", go through the tutorial, and then finish the tutorial. Once click "Editor", make your cell, and click "Finish", press "esc" on your keyboard, then click "Exit to Main Menu" and then click "New Game" it will crash your game. If you skip the tutorial, your game will NOT crash with the same bug.
I have included an attached picture of the "Log Output", which I hope helps the developers fix this bug.
Side note: I have been able to replicate this bug every time I tried to, which has been over 6 times.
