Rendering image returns Null data So, I followed a tutorial on youtube and got a still image render, but after I moved the camera to get a different angle to record an animation, rendering no longer works and just returns a null / blank image.
I am rendering in Cycles.
It's a simple scene, with only a single camera.

Using 0 on the numpad shows the area framed that I want.
I've made sure the camera is selected for the scene.
All items in the scene are rendering (I checked the using the filters for the collection of objects).
The camera is in the same collection as the rest of the objects.
All the objects have a surface.

What have I missed?

I didn't find the reason for the strange behaviour. There must be something wrong in the scene settings, maybe someone can investigate further.
But when I made a new scene, copied all objects from the old scene to the new one, everything rendered fine. Do not try to copy the old scene by using Full Copy, in this case the new scene won't render either.
This is just a workaround to help you rendering the animation. Hopefully someone finds a better answer.
