OBS won't open 80% of the time due to an issue with com.apple.coreaudio.AQClient

[thenightwatch]

Mac Studio
Ventura 13.4
OBS v29.1.1

OBS won't launch most of the time. It takes several tries and usually a reboot. Console reports that a thread usually crashed and that there's an issue with com.apple.coreaudio.AQClient.

Here's the crashed thread. It's always the same.

Any idea what's going on and how to fix this? I can no longer live stream. That's come to a complete stop.

Thanks for any help you can provide.

I've been having a similar issue. My OBS launch log stops at "ffmpeg_options" and the console always shows a crash of "Replayd" with threads related to coreAudioAQclient. I think it may be to do with ScreenCaptureKit somehow.

Often a restart will "fix" it, but yesterday half a dozen restarts didn't help, and I finally managed to get OBS to open by zipping up the "Scenes" folder in OBS-studio, launching OBS--which worked instantly--then closing OBS, restoring my Scenes, and launching again. I have no idea why that worked, but it might be worth trying for you

I have a bunch of crash reports and intend to file a bug report on Github if it keeps happening after the Sonoma update today. Unfortunately, even though it happens every few days, I don't know how to reproduce the behavior reliably, and it's been going on for months.

I also have a Mac Studio, running OBS 29.1.3, and Ventura 13.6 (though I expect to update to Sonoma when it launches today).
