Hi! A heads-up in case anyone else lands here with the same symptom.
After updating to OBS 33 (Windows 64-bit), OBS crashed on launch with a dialog titled "JUCEWindow: obs64.exe – stack-based buffer overrun". Because the JUCE name was in the title, I assumed it was atkaudio. I was on 0.35 and also tried the 0.36.0 pre-release, with the same crash on both.
It turned out atkaudio wasn't the cause. I split my scene collection into halves and tested each one until I found the problem. Removing every atkaudio source still crashed, while a blank collection with a fresh PluginHost2 and my full Waves VST3 chain loaded fine. The real culprit was xObsAsyncImageSource 1.1.0: any collection containing an "Image (Async)" source crashed on launch. Once I switched those sources to the built-in Image source and disabled that plugin, OBS 33 launched normally with my full atkaudio setup (MOTU M2 ASIO through PluginHost2) intact.
My guess is that the JUCE window just happened to own the thread or window when the overrun was caught, so the dialog took its name. I'm posting this so nobody chases atkaudio for that error. Thanks for the plugin, it's the core of my audio setup!
