Render preview and render different

my render is not seen in the same way in the render preview as when you render the image and I do not know why it can be. Does anyone know why it can be or how to solve it?

Check your outliner tab:

You probably have something set to not show in view and show in render ?
Or a modifier set to only affect the render.

The artifacts on the render picture make me think there’s geometry z-fighting.
