Material previews for ShaderGraph materials keeps resetting when entering play mode

Material previews for ShaderGraph materials keeps resetting when entering play mode.

Sometimes they don't render at all afterwards.

Repro steps:

• download the attached project https://drive.google.com/file/d/1u2UPlJULOjRtKe-hwUOeKcOGXwvVUIu4/view?usp=sharing
• enter play mode

Expected result:

All the materials in Project view that have not been edited stay the same

Actual result:

Only material 14 has the correct preview. Materials 12 and 13 now have the generic blue ball icon.

 

Reproducible with 2023.2.0b2 and Shadergraph version 16.0.3
Cannot repro with 2023.1.071 and ShaderGraph version 15.0.6
