Issue using pyvistaqt QtInteractor on Windows 10

[scostiit]

Hello.
I'm trying to use pyvistaqt on Windows 10 but I have some issues.
If I try to execute this code:

import sys
import pyvista as pv
from PyQt5.QtWidgets import (QApplication, QHBoxLayout, QMainWindow, QWidget)
from pyvistaqt import QtInteractor

class MainWindow(QMainWindow):
	def __init__(self):
		super().__init__()
		self.actor = None
		central_widget = QWidget()
		window_layout = QHBoxLayout()
		self.setCentralWidget(central_widget)
		central_widget.setLayout(window_layout)

		self.plotter = QtInteractor(self)

		sphere_f = pv.Sphere()
		self.actor = self.plotter.add_mesh(sphere_f)

		# Set up page
		window_layout.addWidget(self.plotter)
		return


if __name__ == "__main__":

	print('Using QtInteractor')
	app = QApplication(sys.argv)
	window = MainWindow()
	window.show()
	sys.exit(app.exec_())

the program freezes in line self.plotter = QtInteractor(self).

During test I found out that if I use pv.Plotter before the QtInteractot I don't have any problems and the program works correctly.

if __name__ == "__main__":
	print('workaround')
	p1 = pv.Plotter()
	p1.show()

	print('Using QtInteractor')
	app = QApplication(sys.argv)
	window = MainWindow()
	window.show()
	sys.exit(app.exec_())

The original code in Ubuntu 20.04 has no issues.

This is the scooby report of my Windows machine:
