Win10(64bit): VST3PluginTestHost quits silenty on start

When I start VST3PluginTestHost, I see the splash screen and the init phase gets to “Initializing: Audio System” and then the app closes or crashes silently (no error messages).

Any ideas on what could be wrong or suggestions on where to look for log files etc?

System: Windows 10 22H2 64bit

I’m seeing this exact issue but on Windows 11.

the same….Can any official person watch about this?

Did you install the Asio driver by default, delivered with the VST SDK?

vst3sdk\bin\Windows_x64\Steinberg_Built_In_ASIO_Driver_64bit_Installer_1.0.9.zip

seeing the same issue here (ASIO driver installed and rebooted).

the debugger tells me:

The debugged process stopped because it triggered an exception.

Stopped in thread 0 by: Exception at 0x1400b41a3, code: 0xc0000005: read access violation at: 0x0, flags=0x0 (first chance).

… which somewhat implies a nullptr dereference …

I managed to solve this issue with the following steps:

  1. Uninstall the Steinberg ASIO driver

  2. Launch the VST3PluginTestHost

  3. Close the TestHost

  4. Re-install the ASIO driver

  5. Launch the TestHost and select the ASIO driver

    This did the trick for me. Don’t know how or why.

I found the bug and will be fixed in next update of the SDK..
