I am facing the exact same issue: qt.qpa.plugin: Could not load the Qt platform plugin “xcb” in “/home/adminuser/venv/lib/python3.11/site-packages/cv2/qt/plugins” even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

This is the github link: GitHub - sarthak9793/Virtual-Interactive-Board: Air Canvas is a digital drawing and painting platform that lets you create art in mid-air using motion-sensing technology

I would appreciate it a lot if you could help me out!

This error is probably due to the cv2.imshow instruction which does not work on Streamlit Cloud, as we are dealing with a headless environment here.

However, your whole approach with cv2 on Streamlit Cloud will basically not work anyway.
