Простой пример Hello World, взятый из https://doc.qt.io/qtforpython/tutorials/basictutorial/widgets.html

from PySide2.QtWidgets import QApplication, QLabel
import sys
import os

# Set environment variables
os.environ['QT_DEBUG_PLUGINS'] = '1'


app = QApplication(sys.argv)
label = QLabel("Hello World!")
label.show()
app.exec_()

Я получаю сообщение об ошибке ниже:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" 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: eglfs, minimal, minimalegl, offscreen, vnc, xcb.
