Bias Pedal VST Crashing Cubase 9.5 on exit

Was able to isolate the plugin to consistently crash Cubase 9.5 on exit.

Steps to reproduce:

  1. Create an audio track
  2. Insert Bias Pedal and select any distortion/overdrive effect (BIAS Pedal Desktop 64-bit)
  3. Save your work
  4. Exit Cubase 9.5 and the following crash will happen (uninstalling the bais pedal desktop plug-in is the only way to fix your project)

The following crash consistently happen on exiting/closing Cubase 9.5 on Windows 7 SP1/16GB of memory. Cubase stays resident then in memory and I cannot kill the process, and thus must reboot my machine.

Faulting application name: Cubase9.5.exe, version:, time stamp: 0x59e6a397

Hi and welcome,

Most probably this will be plug-in issue. But, could you share (via Dropbox or similar) the whole (source) crashdunp file, please? You can find it in the Documents/Steinberg/crashdumps.

Yes, it is definitely the plugin as it’s the only only for me that causes Cubase 9.5 on exit. Have verified by just using the plugin by itself as a stand alone insert. Crashes every time on exit.

I’l post both the crash log, and the log data dump that Positve Grid had me create shortly via dropbox.

Here you go. There are no crashdump files in the directly unfortunately. WHen bias pedal crashes, it keeps Cubase 9.5 in memory, and I can’t kill the process. My guess is it never gets a chance to write the crashdrump as best as I can tell. I have included the info from the bias pedal dump below though.

The Dropbox link is below:

Here is also the problem details screen from the Cubase 9.5 windows (win 7) and the latest version of Bias Pedal has stopped working screen:

Unfortunately I cannot resolve this.

The ntdll.dll is a general Windows library. But the question is, why does it crash?
