Place QT Window in the middle

[AlphaInc]

Hello,

I'm working on a Python Tool with Qt6 (I have created the UI with QT Designer) but I'm running into a few problems...
This is my code so far:

#!/usr/bin/env Python3

# Imports
from PyQt6.QtWidgets import QApplication, QMainWindow
from PyQt6.uic import loadUi
from PyQt6.QtCore import Qt
import ctypes
import json
import sys

# Main Function
def main()
    window()

# Window Function
def window()
    # Load Config Information from JSON
    with open ('config/config.json', 'r') as fp
        data = json.load(fp)

    # Create Variables from JSON
    for i in data
        for j in data[i]
            for k, l in zip(j.keys(), j.values())
                globals()[k] = l

    # Create Application and Window
    app = QApplication(sys.argv)
    window = QMainWindow()
    loadUi(config/MainWindow.ui, window)

    # Get DPI Scale
    user32 = ctypes.windll.user32
    user32.SetProcessDPIAware()
    dpi = user32.GetDpiForSystem()
    scale_factor = dpi  96

    # Get Screen Size
    screen = app.primaryScreen()
    size = screen.size()
    screenWidth = round(size.width() * scale_factor)
    screenHeight = round(size.height() * scale_factor)

    # Set Static Size and Disbale Menu Bar
    window.setGeometry((screenWidth - window.width() // 2, (screenHeight - window.height() // 2, int(screenWidth // float(Size)), int(screenHeight // float(Size)))
    window.setWindowFlags(Qt.WindowType.FramelessWindowHint)
    window.show()

    # Start Close Button
    window.closeButton.clicked.connect(app.quit)
    window.resizeButton.clicked.connect(lambda window.resize(750, 100))

    # Start the Application Loop
    sys.exit(app.exec())

# Start Main Function
main()

#End
sys.exit()

I'm trying to place the Window in the middle of the screen I'm starting it (not on my primary monitor). For explanation, I used the scale_factor because the window.height and width does not give the right screen size (2560 instead of 3840)... Every time I start the tool the window is not in the middle of the monitor.
I tried to this in Lazarus once and it worked really fast but here I'm having problems... Can someone help me?
