Playback does not work after making timeline changes (v24.2.0 Beta)

Hey y'all!

I have been liking the program, and started using PP Beta for the Audio Enchancement feature. However, I am experiencing an issue with playback when I make a timeline adjustment. I close then reopen the app, and the source footage plays, but everything stops working when I begin making adjustments to the timeline including playback on the source footage itself.

I have tried troubleshooting this by clearing the cache, and killing the app and reopening it several times.
