To reproduce:
1. Create a new HDRP template project
2. Create a Lit Shader Graph in the Project window
3. Double click it to open Shader Graph Window

Expected result: graph is opened without errors
Actual: getting a "The PickingMode enum does not contain the value `Hidden`. Value must be in range [Position | Ignore]." error in the console

Reproduced on:
2022.1.0a15

Not reproduced on:
2022.1.0a14

HDRP package version: 13.1.0

Notes:
- Closing Shader Graph window and opening it again also reproduces the issue
- Tested on Win11
