*Go to the "controls" menu in settings.
*Press the (x) to "unbind action" (I was unbinding one of the inventory buttons).
To Note: The crashing is inconsistent, as sometimes "action unbinding" will not crash the game, or at least not with one click. Also, if clicking "unbind action" does not crash the game, nothing happens anyway, so the button is broken already. Luckily "rebinding" a key works just fine for now.
