Bug object not set to an instance of an object in unity ScriptableRenderer

I'm currently making a fps game and when adding enemies to the game and deleting them from my scene (because some parts didn't work) this error started to appear in my scene. I've never seen this error before and it leads me to a script that's build in in unity. I've tried downloading a repository from a friend who doesn't have this issue and now I have the same error again. I don't get why I have the same error in another project when it worked before

help pls


the full error is this:
