So after loosing an animation to this crash I found I could reproduce it. It happens when the animation editor opens the Context Help window when it’s been previously docked and closed.
Repro
0. Open a new place
Open the context help menu and dock it somewhere and then close it
then close it and open help from the animation editor studio crashes. I don’t know if there are any other combination of actions that cause this but that’s one.
edit: It also seems docking it back to the side of the screen after the split configuration causes the crash.
