@omkar1117 The entire section is a FIXME right now due to the recent introduction of the enableGUI variable. The actual logic is roughly like this:

if enableGUI:
    if state.curses: # non default GUI
        if check_curses:
            gui_curses_and_never_return()
        else:
            complain_no_curses_and_exit()
    else: # default GUI is PyQT
        if check_pyqt:
            gui_pyqt_and_never_return()
        else:
            complain_no_pyqt_and_exit()

# no GUI code past this line
