Запускаю самый простой код из гайда, и ловлю такую ошибку:
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
ps:
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QApplication, QMainWindow
import sys
def application():
app = QApplication(sys.argv)
window = QMainWindow()
window.setWindowTitle('Симулятор JZ')
window.setGeometry(300, 300, 500, 500)
window.show()
sys.exit(app.exec_())
if __name__ == "__main__":
application()
