    Hey folks,

    I've recently upgraded to 2019.2.4f1. When running scenes in my game I'm occasionally getting this error appearing in my log:



    I say occasionally because if I restart Unity and then play the same scene it doesn't appear. I'm not sure what is causing it to appear as yet.

    Has anyone encountered this before?

    This will happen when you are running the game (hitting Play) and then modifying something in the inspector/properties window. It's especially the case when using Booleans (Clicking on a tickbox to enable or disable something while running the game).

    Same here, using Unity 2020.2.1f1. Seems harmless, but seeing errors all the time is annoying.

    I find an answer here:
    It is a Unity bug caused by the inspector window.
    Closing the second inspector window solved this issue.

    After using timeline signals, an exception began to appear when a project is being built in Unity:

    SerializedObjectNotCreatableException: Object at index 0 is null
