    Description

      I'm following this documentation : https://doc.qt.io/qt-6/quick3d-lightmap.html#baking-lightmaps

      *with MinGW kit, the baking was successful.

      [How to reproduce]

      1. Download the attached project and configure it with Qt 6.6.0 MSVC 2019 Kit
      2. Build it with Debug
      3. Run it with --bake-lightmaps
      4. --> Error dialog gets displayed

       [Error dialog]

       

      [Error message(last line) + output]
