An error occurred while listening for keyboard events

An error occurred while listening for keyboard events:
My code:

package main

import (
	"fmt"
	"fyne.io/fyne"
	"fyne.io/fyne/app"
	"github.com/fyne-io/examples/img/icon"
	"github.com/go-vgo/robotgo"
	"hchw.com/note/components/input"
)

func main() {
	ap := app.New()
	hw := ap.NewWindow("hidded")
	hw.Hide()
	editor := input.NewInputUI()
	go listen(ap, editor)
	ap.Run()
}

func listen(ap fyne.App,editor fyne.CanvasObject)  {
	var w fyne.Window
	for  {
		//window.Hide()
		show := robotgo.AddEvents("1", "ctrl")
		if show {
			fmt.Println("pressed ctrl + 1")
			if w == nil {
				w = ap.NewWindow("Gist Editor")
				w.SetContent(editor)
				w.Resize(fyne.NewSize(330, 580))
				w.SetIcon(icon.TextEditorBitmap)
				w.SetOnClosed(func() {
					fmt.Println("windows is closed!!!")
					w = nil
				})
			}
			w.Show()
			w.CenterOnScreen()

		}
		//time.Sleep(10 * time.Second)

		hide := robotgo.AddEvents("2", "ctrl")
		if hide {
			if w != nil {
				fmt.Println("pressed ctrl + 2")
				w.Hide()
			}
		}
	}
}

Error log:

AddEvents() itself is asynchronous, you can use low-level event monitoring.
