Fails to load Master node, Property Window, and Main Preview in shader graph and throws an error.

Steps to reproduce:
1. Create a new project.
2. Windows > Package manager > Shader graph.
3. Windows > Package manager > LWRP / HDRP.
4. Project Settings > Graphics API > Metal
5. Project > right-click > Create > Shader > Unlit/PBR/Subgraph.
6. Open created graph.

Actual Result:
