'13.6' is not a supported ABI version

Hello, I have a problem with building a package. With the command python3.11 setup.py build comes the following error: [ 38s] /usr/bin/python3.11 -c from sipbuild.tools.build import main; main(); --verbose --no-make --qmake /usr/bin/qmake6 [ 38s] Querying qmake about your Qt installation... [ 38s] /usr/bin/qmake6 -query [ 38s] -c: '13.6' is not a supported ABI version This somehow points to a bug in one of the python sip packages, right? If I am correct, is this known? Or do I need to change something in the build? I'm just not getting anywhere at the moment. Maybe someone can help me? Regards Eric
