Error starting an application

[MrMizinov]

Hello, the first time I ran the application I got this error: starting key listener.. listening resetKeyPrsd() 148 2 showWindow() WARNING: QApplication was not created in the main() thread. QObject::moveToThread: Current thread (0x7fdacc000ee0) is not the object's thread (0x7fdacc23fa50). Cannot move to target thread (0x55bd23364d10) qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/paul/.local/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. Available platform plugins are: xcb, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx.

Reinstalled the opencv library:

pip uninstall opencv-python && pip install opencv-python-headless

After restarting I get the following error:
