When every set in gr.Button.click, the inner function cannot get live camera images

[P2Oileen]

Describe the bug

I am trying to show the camera image, but when I set button.click(every=xxx), it cannot get any image. This problem doesn't happen when I delete every=xxx and click the button by myself.
