URP not working in unity 2020.2.1

I recently switched from unity3d 2019.1 to 2020.2.1 but when i setup the URP(Universal Rendering Pipeline) and updated my textures and shader all the materials remain pink but the terrain layers are fixed.I then tried using shader graph but the shader is remained pink.

the image is in the link below

the pink plane is the water shader among others objects and the terrain is the colored islands.

What shader are you using for the water? The best shaders to use for URP are the Universal Render Pipeline > lit and Complex Lit.

Can everyone switch to this page plz,
