Dear all, a proper fix has been added with https://github.com/FreeCAD/FreeCAD/commit/c7a21ecbeecefe7c2dfc9e950b3d6bb42351d476 This means that the function PyConfig_InitPythonConfig must be replaced with PyConfig_InitIsolatedConfig.
The error occurred because PyConfig_InitPythonConfig parses all program arguments while the latter method doesn't. So far only builds with Python 3.11 or higher are affected. BR, Werner
