It’s really weird, cause that variable looks fine, and I’ve tried:
-Duplicating variable and deleting original
-Instead of using an array, just have a mainmenulib variable, and deleting that local variable completely
-Cut connection from start of function, aka do nothing
-Replace old function with a completely new one
And none of these worked! :S I guess it’s some sort of corruption of some sort… sigh
I’ll probably just wait until your next update and replace all the stuff with your new stuff 
Thanks for your help!
EDIT: Aight, so when I never use the ControlsSettingsDetails widget at all, then the menu runs! So I guess I’ll just create a new details widget and hope it works!
