Setting screen does not open

Thank you very much. I will try

Set your phone to Airplane mode and enable WiFi connection.

More than that, enable GPS connection.

And then try to connect C5 app.

wi-fi is connected. An error is displayed when you press the setting button of app.

The application version is v.3.6.2.

android is version 9.

The device has been upgraded last year.

Is there a solution?
