Camera not rendering to display, but world shows up in gamescreen

I have a camera that works fine on its own. When applying a render texture it the display tells me no camera is rendering. When correctly applying a raw image to the rendering texture which was what i aimed to do the game screen renders the world but the display 1 error message ramains on screen. It appears my camera is somehow deactivated and still not activated after applying a raw image, a method which i learned from en example online and for which it worked.
I also think I remmeber the error message disappearing for a short while before coming back after a while and now not wanting to disappear…

Glad for any help!
