wxPython：从RS232接口循环更新wx.ListCtrl数据表崩溃求助

我正在开发一个从RS232接口循环读取数据并显示在wx.ListCtrl中的程序。目前数据每秒更新一次，但更新wx.ListCtrl时程序崩溃，崩溃信息如下。我怀疑当前GUI控件不适合该场景，希望获得RS232流文本表格的可视化替代方案。

此前用控制台输出数据更新无问题。

代码片段 #

def OnConn(self, event):
        """Say hello to the user."""
        # configure the serial connections (the parameters differs on the device you are connecting to)
        ser = serial.Serial(
            port='COM11',
            baudrate=115200,
            timeout=1,
            parity=serial.PARITY_NONE,
            stopbits=serial.STOPBITS_ONE,
            bytesize=serial.EIGHTBITS
        )
        retConn = ser.isOpen()
        wx.MessageBox(f'Connection Open = {retConn}')
       
        while 1:
                bytesToRead = ser.inWaiting()
                data = ser.read(bytesToRead)
                time.sleep(0.5)
                dataRS232 = data.decode("utf-8")
                # Add the rows
                for item in dataRS232:
                    index = self.list.InsertItem(self.list.GetItemCount(), item[0])
                    for col, text in enumerate(item[1:]):
                        print(f'index = {index}    column =  {col}    text = {text}')
                        self.list.SetItem(index, col+1, text)
        ser.close()
