    In my case, I'm not removing any VFXRenderer. I have simple scene with one VFX and it crashes either when I try to edit the VFX or when I press "Play". I also tried on another computer with a new project, same issue.

    I'm using the packages : entities and (with URP). Maybe they're not compatible with the VFX Graph?

    This is currently being backported to 2022.2.
    The issue occurs when you remove the VFXRenderer component while the gameobject is disabled.
    Manually removing the VFXRenderer is not recommended, but if you have to do so, just make sure that the gameobject is enabled when you do, as a workaround.

    I have the same issue with Unity 2022.2.11f1. Is there any workaround? I couldn't find any.
