Disposing an InputControlList in a RebindingOperation like stated in Struct InputControlList<TControl> | Input System | 1.3.0 and gotten here: Class InputActionRebindingExtensions.RebindingOperation | Input System | 1.3.0 as candidates causes a crash in the Player some seconds after the RebindOperation completion handler returned, in some Jobs thread of Unity, not of my code, I don’t use Jobs anymore. It does not cause a crash inside the Editor, there also is no debug message regarding this inside the Editor with all Debug combinations of Jobs tested.
I tested this with 2022.1 Beta 9 and InputSystem 1.0.2, 1.1.1, 1.2.0 and 1.3.0.
This did not occur in some 2020.1 and InputSystem <= 1.0.0
