    Contradictory information! Up above this ticket states:
    "Fixed versions:

    While here -
    "Known Issues in 2018.4.23f1

    So what?

    It's considered as fixed in Unity 2019.3.14, but in fact it's still happening, please re-open this issue!

    I'm using Unity 2019.3.12 and I receive this error on my Particle System. It will randomly appear between 1 to 5 minutes after run time. If I deactivate the gameobject it never appears, is there a way to resolve this error?

    In my case I am having the same problem with the line renderer.

    If you disable the Gameobject that contains the line renderer, no symptoms appear.

    Unity 2019.3.12f1

    EDDYSPAGHETTI, it does. I have players reporting crashes because of this issue. It's only on some machines, but it happens.

    Having the same issue in 2019.3.11f1, pretty infrequently. I'd love to know the answer to whether or not this has an impact on built games. It LOOKS like it might be an editorGUI only issue, which means we can at least proceed with working in this version while we wait for a fix to land for 2019.3

    Does this impact the final build in any way? Or is it just outputting the error message as an error in itself? Should I worry about publishing with these error messages?
