Bug when changing screen with a clock

Hello, I’m creating my app, and I want to make a home screen: the problem is that as soon as it changes to the Menu screen, an error is displayed: Cannont find the component " State_progress_bar1 ", while I have no instructions that use this on my screen. Even more bizarre: at the same time that this error appears in a pop-up, I am redirected to the loading, in loop.

Thank you in advance :slight_smile:

first of all when timer do, disable clock timer, because that will create a endless loop and will open and screen again and again.2nd first close screen and then open another screen.
