`RuntimeError: PyQt6.QtWebEngineCore cannot import type 'QModelRoleDataSpan' from PyQt6.QtCore` after install

[Thysrael]

Describe the bug After I following README to install eaf, I try to run eaf-open-demo or eaf-open, eaf didn't work.

To Reproduce Yes I git clone the newest update of eaf. And I run the install_eaf.py successfully(I guess, because nothing wrong happend). I use emacs -Q and eval the code below:

(add-to-list 'load-path "~/.emacs.d/site-lisp/emacs-application-framework/")
(require 'eaf)

(require 'eaf-browser)
(require 'eaf-pdf-viewer)
(require 'eaf-demo)

Expected behavior I hope eaf can work correctly.

Looks your Qt or PyQt not install complete in your system.

Thank you, it fixed.

I remove the pyqt6 installed from pacman, and create a new python venv at eaf directory. It works well.
