Packaging Fails Due to Camera Cut of Sequencer in 4.19

Projects that worked normally in 4.18, failures occurred in 4.19. Resolve by replacing the contents of the LevelSequence that is the cause of the problem with the new asset.Perhaps a problem has occurred in the parameters of the camera cut track.

A licensee shared the reproduction project. I attached it here.

1. Open attached project
