This problem was reproduced in 5.0 Preview 2.
According to the licensee, this did not occur in 4.26.
Not sure if this is related to the camera manager, but some objects are delayed at the end of sequencer playback.
Unzip the attached project.
Open the project and run it in PIE.
Press the Home key to play the sequencer and confirm that the message outputting the coordinates of the camera manager is delayed by one frame.
