Response error on Windows 11

I tried running the "simple.py" in the example folder on Windows 11. The drone was connected and took off successfully. However, it had no response after sending the "move_left" command. Here is the error message:

It looks like your drone does respond, but with an error message error enter stop.

Have you tried calibrating the drone? What firmware version and what drone are you using?

My firmware version was 01.04.35.01. After updating to 01.04.91.01, it works well now. Thank you very much.
