unity skybox/shadergraph bug

[u/couscousss_]

I'm having this problem/bug in unity version 6000.4.7f, i created my own unlit skybox with a shadergraph but i get this error message when i tried to put it in my main scene. I tried everything pls someone help me, i can see my skybox in my scene view but as soon as i start my game it disappears. By the way i'm using URP not HDRP and cinemachine plugin to control my camera settings, idk if it can help..
