Webviewer camera problem

so i'm working on an assignment using teachable machine extension. the app will be used to detect waste types, and i'm using webviewer as camera and image detector thing. it runs normally, with a home screen and detection screen (the one with the webviewer). but, when i go back to home screen and try to go to detection screen again, the camera viewer is completely white, like it's on but we can't see anything but white. what's the problem and how to solve it?



Switching Screens is very disruptive.

Instead, stick to one Screen and expose different stacked Vertical Arrangements, one at a time, using the Visible attribute.


so I have a task to make a trash sorting app. well I use a webviewer but in my app it can only be used once. I made 2 screens. The first screen only contains a button to go to the next screen and screen 2 contains a webviewer to detect trash and a back button. when I press the next button on screen 1, the display immediately switches to screen 2 and can detect trash. then I press the back button on screen 2 to return to screen 1. then I tried to press the next button again to go to screen 2. but the webviewer can't be used, it's just blank white, it can't detect. what do you think should be added to the coding?
