Unity 2021 - Shader Graph not working

I'm in a brand spankin new project in Unity 2021.1.14f1 using 3D Sample Scene URP. I create a new shader graph > blank shader graph -- and the material is magenta/pink showing it's not compiling. Did no one test this in 2021 or am I doing something wrong?


I also notice whenever I add any node into the scene it shows me this error too... It says "Node is not allowed by any active targets, and will not be used in generation"....
