Android Camera does not show Image

My MainCamera should display an image which is on a canvas. In GameView everything is fine, but when i start the game on an android system, it just shows the solid background color.
Any ideas how to fix this?

Funny fact the same image appears in the menuscene correctly but does not do it in the game itself.

Seems when i have 2 Canvas’s in one scene, one as screen space overlay, the other with scren space camera, the camera one doesn’t show. Switching this one to world space, and all worked.
