PySide 6.5.0: Cannot load library qtquick2plugin.dll

[demberto]

__main__.py

import pathlib
import sys

from PySide6.QtGui import QGuiApplication
from PySide6.QtQml import QQmlApplicationEngine

from __feature__ import snake_case, true_property  # type: ignore # noqa

if __name__ == "__main__":
    app = QGuiApplication(sys.argv)
    engine = QQmlApplicationEngine()
    engine.load(str(pathlib.Path(__file__).parent / "welcome.ui.qml"))

welcome.ui.qml:

import QtQuick
import QtQuick.Controls
import QtQuick.Layouts

Window {
    title: "MyWindow"
    visible: true

    RowLayout {
        anchors.fill: parent

        Button {
            text: "B1"
        }

        Button {
            text: "B2"
        }
    }
}

This results in an error:

QQmlApplicationEngine failed to load component
file:///.../welcome.ui.qml:1:1: Cannot load library ...\Lib\site-packages\PySide6\qml\QtQuick\qtquick2plugin.dll: The specified module could not be found.

Just a bump. I am really stuck on this one, can anybody help me out?

The example works fine here, so, it looks like a broken installation. Have you tried re-creating your virtual environment?

@friedemannkleint I tried all that, I tried different versions of virtual environments. Finally I switched over to PyQt6 and now it works flawlessly.
