It's going to be a bit hard to test the patch for getopt.py, as the default
LyX installer ships the Python libraries in a .zip file ("C:\Program
Files\LyX 2.4\Python\python311.zip") containing only .pyc files (like
getopt.pyc).
Nevertheless, copying your module lyxwin_getopt and patching lyxpak.py
solves the problem for me! (Windows 11 x64 23H2.)
