The GUI Library used as your dependency updated yesterday (2025-10-22) and it seems to have introduced a bug within your code. Reverting back to the previous dependency version (0.1.5 instead of 0.1.6) fixes this.
What happens is when I open the Recipe Tweaker GUI the game presents me with an error message and then the game closes to title.
The mod Recipe Tweaker (0.1.5) caused a non-recoverable error.
Please report this error to the mod author.
