Hello! Just installed this mod and every time I click the settings button, I get a crash with the following error:

https://media.discordapp.net/attachments/1197525519869157467/1197525856051003422/image.png

(Also as an unrelated suggestion, a hotkey and/or shortcut button to show/hide the window would be nice.)

I have the same:

The mod Kuxynator's Production Rates (2.2.2) caused a non-recoverable error.
Please report this error to the mod author.
