Background color picker not updating background

hello. I’m having a weird problem that just started. When I try to change the scene background color, it instead changes the color of the ground shadow. i don’t have any planes in the scene - nothing obstructing, Also, when I try to change the color in the HDRI Editor, it changes the color of the material reflection instead. Does anyone know what is causing this? Thx!

my guess is the image style
check, if you activated the overlay
