No playback!

24.2.0

Mac Studio M1 Max 64GbRam

Sonoma 14.1.2

Opened a project with 2 sequences and perhas 50 clips.  I could get the project to playback 1 time then all freezes.  Program and source windows become unresponsive.

MIGHT be rekated to enhancing audio.  When I exported the sequences as XML and re imported into a new project, playback is restored
