Constraint Actor to Rig with Editor Utility Widget is working for the first time adding to the Sequencer.
However if it was deleted and added to Sequencer again, run Scripted Actor Action shows Errors in the Output log, showing that Constraint were not added.
It appears that the error occurs because UTransformableControlHandle::GetBoundComponent() returns nullptr for the second error case. In the first case, it returns a valid skeletal mesh component.
This was also tested on CL 34066942 in UE5_Main and the launcher version on 5.3.
