Description

A crash inside Unreal Engine Editor version 5.4.4 occurs when reproducing a Level Sequence while in PIE. This issue is a regression. It only crashes in version 5.4.4. It was working correctly in version 5.4.3.

For this crash to occur, these prerequisites are needed:

· Add a Camera to the Level Sequence
· Add a Camera Shake to the Camera added previously.
· A Camera Shake track needs to have the same duration as the sequence.

The user in the related case has already added a repro project that crashes the engine. If the project does not crash immediately, just adjust the length of the camera shake track to the length of the LevelSequence.

Steps to Reproduce

With the reproduction project:

1- Open the project and PIE. After the first reproduction of the level sequence, the engine will crash.

Without the Repro Project:

1- Create a Level Sequence
2- Create a Camera Shake asset
3- Open the Level Sequence, and add a spawnable Camera
4- Add the Camera Shake to the camera spawned in the sequencer
5- Adjust the Camera Shake length to the Level Sequence length.
6- Open the LevelBlueprint and create LevelSequencePlayer to run the LevelSequence with the SeetingsLoop set to -1.
7- From the LevelSequencePlayer play the LevelSequence.
8- Now PIE, and let the LevelSequence play and loop. It should crash at the end of the first run.
