P.S. I forgot I'm using another OBS for recording, so you can't hear what's the plugin sound like, but it work find.

Additional information

Only "pitchproof" will lead to Obs crash, I tested another plugin "GSnap" (which is a autotune plugin) it work totally fine.

Edited

Add plugin download page here:
Pitchproof is a free audio plug-in that can shift the pitch of the input.

I have been able to reproduce this.

Where the error occurs:
https://github.com/obsproject/obs-vst/blob/master/VSTPlugin.cpp#L185

Here's the strangest part - the VST window in this case is titled based on the name of another filter, not the source itself.

Looks like this is an issue with the VST plugin if it's crashing inside the DLL after calling close.

Closing as this appears to be an issue with the plugin itself, not the OBS VST plugin. However, that said, if the plugin developer wishes to contest that, this issue should be reopened on the obs-vst repo instead.
