title: Qt6 for Python (PySide6) on Windows 10: can't make QtQml and QtQuick work from QML
body: <p>On my Windows 10 machine I'm trying few simple examples of new Qt6 and QML based example doesn't work for me.</p>
  <p>I'm running Python 3.8.6 and a virtual env</p>
  <pre><code>python3 -m venv venv
  .\venv\Scripts\Activate.ps1
  </code></pre>
  <p>The pyside6 installs without any warnings into the venv</p>
  <pre><code>pip install pyside6
  </code></pre>
  <p>and a non-QML hello world example using QApplication and QLabel runs fine (this one: <a href="https://doc.qt.io/qtforpython/tutorials/basictutorial/widgets.html" rel="nofollow noreferrer">https://doc.qt.io/qtforpython/tutorials/basictutorial/widgets.html</a> )</p>
  <p>What doesn't work is this example, taken from <a href="https://doc.qt.io/qtforpython/tutorials/basictutorial/qml.html" rel="nofollow noreferrer">https://doc.qt.io/qtforpython/tutorials/basictutorial/qml.html</a> :</p>
  <p>main.py:</p>
  <pre><code>from PySide6.QtWidgets import QApplication
  from PySide6.QtQuick import QQuickView
  from PySide6.QtCore import QUrl
  
  app = QApplication([])
  view = QQuickView()
  url = QUrl(&quot;view.qml&quot;)
  
  view.setSource(url)
  view.show()
  app.exec_()
  </code></pre>
  <p>view.qml:</p>
  <pre><code>import QtQuick 2.0
  
  Rectangle {
      width: 200
      height: 200
      color: &quot;green&quot;
  
      Text {
          text: &quot;Hello World&quot;
          anchors.centerIn: parent
      }
  }
  </code></pre>
  <p>the messages I receive trying to run are:</p>
  <pre><code>file:///C:/github/aorcl/python-gui-2/view.qml:1:1: Cannot load library C:\github\aorcl\python-gui-2\venv\lib\site-packages\PySide6\qml\QtQml\WorkerScript\workerscriptplugin.dll: The specified module could not be found.
       import QtQuick

  </code></pre>
  <p>I verified and the file isn't missing, it is there:</p>
  <pre><code>C:\github\aorcl\python-gui-2\venv\lib\site-packages\PySide6\qml\QtQml\WorkerScript\workerscriptplugin.dll
  </code></pre>
  <p>What else am I missing?</p>
