Hey Chris,

OBS (Open Broadcaster Software) that many people use to stream and record video for online video content has (limited) support for VST 2.x plugins. OBS Studio recognizes Airwindows plugins (they should be installed/simlinked in /Library/Audio/Plug-Ins/VST/, that is, relative to root, not relative to the home as in ~/Library/Audio/Plug-Ins/VST/) but crashes and won't load the UI for the handful of plugins I tried on my computer (Console4 being the first I tried).

I am on macOS 10.14.6 (18G103) and OBS Studio 24.0.6 (64 bit).

Steps to repro:

Download and install OBS Studio 24
Install/simlink the VSTs to /Library/Audio/Plug-Ins/VST/
Create an audio filter, add a VST 2.x effect, and then select an Airwindows VST (for repro, lets say Console4Channel)
Select Open Plug-in Interface
No window opens for me, the button just changes to Close Plug-in Interface
Now change the VST (for repro, say to Highpass2)
OBS Studio crashes

The general pattern here works for me regardless of what plugins I select---the first won't open the VST UI, and then whenever switching to another VST, OBS Studio crashes.

On a wiki page on OBS's GitHub, they list some example tested free VSTs here: https://github.com/obsproject/obs-studio/wiki/Filters-Guide#vst-plugin. I tried a handful of the free Melda Productions VSTs with no problems.

As OBS is also freeware, I figured it might be up your alley to investigate if possible. Since it's not clear where the problem lies, I am also opening up an issue on OBS's GitHub.

Thanks!
