It does not happen if using the normal release (non-beta) version of OBS.
I remotely debugged this on a user's machine by using xctrace (command-line version of XCode Instruments).
Platform: M1 Max MacBook Pro 16 running Sonoma 14.0, FCP 10.6.10.
Symptoms: within about 20 seconds of playing any video file, FCP would hang. This happened despite all external hardware being removed. It did not hang if booted in Safe Mode.
The Instruments trace showed the main UI thread spawned an excessive number of CVDisplayLink threads (over 150), then FCP hung. Annotated Instruments trace: https://joema.smugmug.com/XCode-Instruments-Dominic-FCP-Hang/n-RnV7hH/
