Every Neural DSP plugin I try to load in Beta 4 hard crashes the app. My other amp sim plugins load fine, it seems specifically related to Neural DSP.
I think the first thing people are going to say is make sure that you are using a 64-bit plug-in with a 64-bit version of Audacity. Same thing with 32-bit.
But you probably already knew that.
All my plugins and the Audacity 4 beta are 64bit versions. So that’s not it I’m afraid. Something in the NDSP UI’s seems to trigger the crash, but the app doesn’t give me any crash logs which seems strange for a beta.
