PowerApps Set(varName, camera1.stream) not working

Hello.

I am trying to get an image from "Camera" control by using a variable and then assign this value to the "Image" media control.

When the button is clicked then variable assigned to camera.stream value.

Set(varName, camera1.Stream)

I don't know what happened but now this method not working.

Variable does not take the camera1.stream value.

In my previous programs, all are working fine.
