I noticed the same kind of behaviour with the plugin. Biab Standalone seems to work normal.
Not sure where exactly it comes from, but the plugin generates .wav files with size but without content in the folder \bb\plugin\saved tracks.
Recently I had updates on my RME UFX windows audio driver, a Samplitude X8 and a Biab update including biab plugin update to version 6.1.8.
I doubt that it has something to do with the RME driver or Samplitude, as the behaviour with Samplitude X7 is the same and it had been working in the past.
