    Description

      1. Use the MaintenanceTool to install Qt Quick 3D Physics.
        The dependencies Qt Quick 3D, Qt Quick Timeline and Qt Shader Tools are silently installed, too.
      2. In Qt Creator, open the Car Configurator demo from the Welcome mode.
        It's in Examples\Qt-6.9.0\demos\car-configurator\CMakeLists.txt
      3. Set a short build directory to work around QTBUG-132551.
      4. Try running the demo.
        It starts up, shows a mostly black screen which is badly scaled on an UHD screen and the just crashes: 
        18:08:07: Starting D:\Qt\ShortBuild-MinGW\CarRenderingApp.exe...
qt.gui.imageio: libpng warning: iCCP: known incorrect sRGB profile
D3D11: Removing Device.
Device loss detected in Present()
Graphics device lost, cleaning up scenegraph and releasing RHI
18:08:23: The process crashed.

      The crash does not seem to happen when using Qt for MSVS2022.
