Unity 2019 - Error with keepAnimatorControllerStateOnDisable

I've updated my project from 2018.3.8f1 to 2019.1.0f2 and I can no longer use the setting on my Animator Controllers to keep the state on disable. This is the code I have:

foreach (Animator a in fullObj.GetComponentsInChildren<Animator>())

                    a.keepAnimatorControllerStateOnDisable = true;

And this is the error I get:

Assertion failed on expression: 'm_BindingsDataSet.m_GenericBindingConstant != NULL'
UnityEngine.Animator:set_keepAnimatorControllerStateOnDisable(Boolean)

I can't find another way to set this value other than to manually set it on each object in the editor through the Debug inspector of the Animator component... which is inconvenient, and really this should work.

 

Bump

 

Happening on 2018.4.2 as well

Any bug reports on this?

 

You should report this as a bug, as well as post a thread in the Animation forum.

 

I am facing the same error now that I updated a project from Unity 2018.3.1f1 to 2018.4.2f1.

This happens when applying

_animator.keepAnimatorControllerStateOnDisable = true;

when the GameObject is disabled.
