FatalError: `Process abort signal` is detected by the operating system.

Hi everyone:
I encountered a problem that caused my PyQt5 program to fail to execute
The error message is as follows:Got keys from plugin meta data ("xcb")

It could be something like https://bugreports.qt.io/browse/QTBUG-112185 (Qt 6), or some other incompatibility of PyQt5 on that distribution. I would recommend updating to PySide6/PyQt6 first thing, Qt 5 is quite old.
To diagnose, run
ldd /home/yuying/anaconda3/envs/Qt_test/lib/python3.9/site-packages/cv2/qt/plugins/platforms/libqxcb.so
and check for missing dependencies.
