        def __inject_wx(_):
            code = textbox.GetValue()
            exec(code, globals())

        def openInjector_wx():
            app = wx.App(redirect=False)
            frame = wx.Frame(None, title="Injector", size=(640, 400), style=wx.SYSTEM_MENU | wx.CAPTION | wx.CLOSE_BOX | wx.MINIMIZE_BOX)
            panel = wx.Panel(frame)
            button = wx.Button(parent=panel, id=-1, label="Inject", size=(50, 20), pos=(295, 0))
            global textbox
            textbox = wx.TextCtrl(parent=panel, id=-1, pos=(20, 22), size=(600, 340), style=wx.TE_MULTILINE)
            frame.Bind(wx.EVT_BUTTON, __inject_wx, button)
            frame.Show()
            app.SetTopWindow(frame)
            textbox.AppendText(defaultText)
            threading.Thread(target=app.MainLoop).start()

        openInjector_wx()

here is the error
