How to generate under Qt 5.15.2 and 6?

[Sepera-okeq]

How to generate code for Qt 5.15.2 and 6? My generator is not working properly:

Please wait while source files are being generated...
Parsing typesystem file [:/trolltech/generator/build_all.txt]
Fatal error: line=1, column=1, message=unexpected end of file

Fatal error: line=2, column=62, message=Failed to parse: 'typesystem_core.xml'

Cannot parse file: ':/trolltech/generator/build_all.txt'

How to fix it, is it a problem of this project? And how to create your own configuration (.xml) files?

And another question. I would like to control which functions can be used in Python.
That is, the ability to cut out functions so that they cannot be used. Is it possible with this generator?
