Answer 1

PyQt6 is installed. Same as PySide6. And by the way, PySide6 is no longer preferred. qt.io bought this package from the former owner some time ago. Although there with compatibility, not everything is smooth. I hardly dragged my small utility from PyQt5 to PyQt6 ...
I still managed to cross PyQt5 and Python 3.10. See my answer here
After finding the PyQt5 and PyPi maintainer's mail, he wrote me that 5.15 will be released within a few days and gave a link to https://www.riverbankcomputing.com/pypi/ , where this version seems to be available.
