Crash when undoing added clips that are currently playing in the Audio Random Container

Unity: Audio Random Container

Fixed

6.0.X

6000.0.6f1 onwards

Fixed a bug that would cause Unity to crash if you perform an undo action in the audio random container window while the audio random container is playing.

Steps to reproduce:

Create and open an empty project.
Import some audio clips.
Create an Audio Random Container (Assets > Create > Audio > Audio Random Container).
Add a clip to the Audio Random Container.
Add another clip to the Audio Random Container.
Preview the Audio Random Container.
While the second clip is playing, perform undo with the shortcut (cmd + Z).

Actual results: Editor crashes.

Expected results: Editor does not crash and any playback of the Audio Random Container asset stops.

Reproducible with versions:
6000.0.23f1

Not reproducible with versions:
6000.0.0f1

Can’t test with versions:
2022.3
2021.3

Tested on (OS): MacOS M1 14.6.1

Notes:

Only happens when issuing the undo with a shortcut.
This also happens if you are in play mode with an audio source playing the Audio Random Container asset.
