As a matter of fact there is no official ocrfeeder release newer than the one in manjaro right now (as it was observed), but a simple patch can fix the issue.
In /usr/lib/python3.10/site-packages/ocrfeeder/studio/studioBuilder.py change add_engines_dialog = widgetPresenter.SystemEnginesDialog(engines) into add_engines_dialog = widgetPresenter.SystemEnginesDialog(self.main_window, engines)
I understand that manjaro and arch do not patch downstream. Some users might find this info useful, though.
There is no issue–at least for me on the unstable branch. Maybe you should switch branches and see if that makes any difference. If not, then it’s a local issue on your machine. Maybe you’re mixing system and user Python packages.
