Error with render when reimporting URP demo pack

Hello, my name is Bruno, I’ve been creating this game for a year or so. I was using an asset from the store, Unity Terrain - URP Demo Scene. and I had to import it again. and when I did that, some objects became invisible. even objects that share the same texture. Some are invisible and others are not.

I FOUND THE MISTAKE, IT WAS MY BLAME LOL.
I had changed the rendering pipe in the graphics settings to one I created.
