Game crashes when pressing Cancel or ESC on the Create New World screen

The game consistently crashes to desktop when attempting to cancel the creation of a new world.

Steps to Reproduce:

1. Start the game and select "Singleplayer".

2. Click the "Create New World" button.

3. On the world creation screen, optionally enter a world name or change any settings.

4. Click the "Cancel" button at the bottom left of the screen, OR press the "ESC" key.

5. The game immediately crashes and generates a crash report.

Expected Result:
Clicking "Cancel" or pressing "ESC" should exit the creation screen and return the user to the previous (Singleplayer) menu without issues.

Actual Result:
The game crashes completely and closes.
