All materials pink in stylized nature pack unity 2020.1

I am new to unity and working on a level design using the stylized nature pack. Once I import the pack all the materials are pink. I have tried to remap the material but it just shows as a pink circle. Any help would be appreciated.

I’m guessing you’re using either Universal Rendering Pipeline or High Definition Rendering Pipeline? You’ll need to convert your materials to SRP-compatible shaders.

You can attempt to automatically do this as described here: Upgrading your Shaders | Universal RP | 7.1.8

got most of my stuff fixed but I cant seem to figure out how to fix the terrain default shader material. Or how to change it. once again any help is appreciated.
