Update:

shiboken could not find QWidget, when targetType is QWidget this line will return a nullptr, only Widget in the list.

Update:

If using homebrew, shiboken argument --include-paths contains /usr/local/include (Qt's include dir), it will trigger segmentation fault, if use /usr/local/opt/qt/include instead, everything is ok, but /usr/local/include contains all files in /usr/local/opt/qt/include...
