Ensure condition failed : Unprocessed LatentActions accumulate by SetPlaybackPostion using Play method

If some sequencer events are added to LatentAction queue while calling SetPlaybackPostion using Play method, the events will not be digested.
So the LatentActions cause that ensure condition failed next tick.

Following workaround resolves this issue.

void UMovieSceneSequencePlayer::SetPlaybackPosition(FMovieSceneSequencePlaybackParams InPlaybackParams)
{
...
	TimeController->Reset(GetCurrentTime());

	RunLatentActions();  // workaround : flush latent actions

	if (HasAuthority())
	{
		RPC_ExplicitServerUpdateEvent(InPlaybackParams.UpdateMethod, NewPosition);
	}
}

1. Open attached project on ue4.27 [Link Removed]
2. Run PIE

Result:

A few seconds later, the following ensure is hit.
