I was able to install pyqt6, but installing pyqt6-tools fails with a MemoryError. One thing to note, memory usage for Python spikes up to 3GB.
Here is the output of running pip install pyqt6-tools:

MemoryError
I have only 8GB of RAM so maybe this is not enough? I am on Qt version 6.9
pyqt6-tools depends on pyqt6-plugins, pyqt6-plugins was last released in 2023, python313 was not around in 2023, so pypi has no pyqt6-plugins wheels for python313 (only for python311), so pip downloads source of said plugins and tries to compile it, and pyqt6 as well (I guess you cannot compile plugins without compiling the whole qt). And that requires a lot of time and memory.
What you can do instead:
If you only need qtcreator you can download if from github.com
