Audio Sync Causes Crash

Opening the Synchronisation menu for audio sync causes Premiere Pro to freeze, forcing me to force quit via the Activity Monitor. This happens 9/10 times, but sometimes works as expected and allows synchronisation.

I have re-installed Premiere completely fresh, removed preferences, etc, and it continues to happen.

Currently on Premiere Pro version 24.3, using a 2022 Mac Studio:

- Apple M1 Max

- 32GB Memory

- MacOS Sonoma 14.2.1

I have attached a video showing the issue where, conveniently, it works the first time, but the second synchorinsation crashes Premiere.
