Cant change background image on videocall

I am somehow stuck with a background image i set a year or so ago Whatever i try i cant change my background image on videocall. I tried looking everywhere in the settings both in and out of calls.

Even on the background options in a call it is set to "none" but the image is still there. How do i remove it completely? It is incredibly annoying that is no simple way to change this..

Note: i am on android
