Steps to reproduce:
1) Download SRP Repo from here: https://github.com/Unity-Technologies/ScriptableRenderPipeline
2) Open ScriptableRenderPipeline >> TestProjects >> LWGraphicstest project in Unity
3) Make sure Vulkan is the only Graphics API in the Player Settings
4) Leave only "027_PostProcessing" scene in the Build Settings
5) Build and Run "027_PostProcessing" scene on a device
Observe crash when application is launched and check the logcat to see printed message multiple times:
