Control UI doesn't show properly, also no video shown, but function work properly.

Hi. Normally, when you run python main.py, the real-time video will be displayed directly on the GUI interface, and you can take photos. So this may be because the video stream is blocked when tello transmits video streams to your PC device. So, you need to check if your PC network settings have disabled the UDP port 11111 for video streaming.
how to check this?
