      Description

      While playing around with the 3d runtime inside the QtDesignStudio with an open preview it crashes with

      >	Qt5Quick.dll!QQuickItem::window() Line 2917	C++
       	q3dsstudio3dplugin.dll!Q3DSStudio3DRenderer::renderOffscreen() Line 144	C++
       	[External Code]

       	Qt5Quick.dll!QSGRenderThread::run() Line 734	C++
      

      code in q3dsstudio3renderer.cpp:

      void Q3DSStudio3DRenderer::renderOffscreen()
      {
          // m_item may be destroyed already
          QMutexLocker lock(&m_itemInvalidLock);
          if (m_itemInvalid)
              return;
      
          QQuickWindow *w = m_item->window();
          if (!w)
              return;
      

      so maybe it is just a check if m_item is valid or maybe set m_itemInvalid if item was destroyed not sure
