PyQt6: AttributeError: 'Config_lod' object has no attribute 'widescreen'

Помогите пожалуйста, никак не могу разобраться, что я делаю не так

main.py:

    def __init__(self, parent = None):

        self.ui = interface_ui.Ui_MainWindow()
        self.ui.setupUi(self)
        
        self.setFixedSize(self.size())
        
        self.widescreen.stateChanged.connect(self.on_checkbox_changed)
        self.autofpslimit.stateChanged.connect(self.on_checkbox_changed)


    def on_checkbox_changed(self, value):
        state = Qt.CheckState(value)
        if state == Qt.CheckState.Checked:
            print('Checked')
        elif state == Qt.CheckState.Unchecked:
            print('Unchecked')
