Unity Crashes if the VFX Graph Package is removed while VFX Graph stuff exists in the Scene

Visual Effects


A crash occurs if a particular workflow occurs with VFX Graph. Judging from the call stack this seems to be a VFX Graph bug, though it could be Package Manager related.

To reproduce:
1) Create a new project
2) Add the VFX Graph package
3) Create a VFX Graph Asset (Assets / Create / Visual Effect / Visual Effect Graph)
4) Create a Visual Effect in the Scene (In the hierarchy: Create / Visual Effects / Visual Effect)
5) Assign the VFX Graph Asset to the Visual Effect in the Scene
6) On the Visual Effect in the Scene, Click on "Edit" - The VFX Graph Editor Window should appear
7) Remove the VFX Graph Package

Unity will then crash!

Note: HDRP package is not installed by default as it is not an explicit dependency of VFX Graph. This could be triggering a problem in the Compute Shader?
