pyside6-deploy Failed unexpectedly in Scons C backend compilation ????

[yoja]

I have been working with pyside6 and qml. but unfortunately I can't deploy the application. I have started a new project but the error continues. Does anyone know how to fix it?:
main.py

import sys
from PySide6.QtCore import QCoreApplication
from PySide6.QtGui import QGuiApplication
from PySide6.QtQml import QQmlApplicationEngine

if __name__ == "__main__":
    #creating the app
    app = QGuiApplication([])
    engine = QQmlApplicationEngine()
    

    #load the qml
    engine.load("Main.qml")


    if not engine.rootObjects():
            print("Failed to load main.qml:")
            exit(1)

    app.exec()

Main.qml

import QtQuick 2.15
import QtQuick.Controls 2.15


ApplicationWindow {
    id:appWindow
    visible: true
    width: 370
    height: 370
    maximumHeight: height
    maximumWidth: width
    minimumHeight: height
    minimumWidth: width
    title: "My App"

}

thanks a lot.

@yoja
I know no more than this: Googling for your missing symbols suggests you may need to pass some -fsanitize=... option(s) to your compilation/link command.

I finally managed to generate an executable using cx_Freeze. Then by copying the directory that contains the .qml files in the same dir of the executable, I made the application run without problems.
Soon I will continue using pyside6-deploy in the way you suggest. Thank you so much

Out of curiosity, have you tried building this with "pure" nuitka (not via pyside6-deploy)? I have completely given up on pyside6-deploy, but never really have any problems with nuitka for any platform.
