Can't use cv2 with PyQt5 on python

hello guys, I am working on a project which requires both PyQt5 and opencv, it worked perfectly on Debian and ubuntu but it is not running on all manjaro os :frowning_face:, I don’t know what I missed but here is the error message.

QObject::moveToThread: Current thread (0x55b215853fd0) is not the object’s thread (0x55b215a473a0).
Cannot move to target thread (0x55b215853fd0)

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/ab/PycharmProjects/ai_security/venv/lib/python3.8/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.
