Hi D K,
Sorry to hear about the crashes. I took a look at your fault report submissions and they're identifying the crash site as the Steven Slate Virtual Channel (Automap).dll.
A few places I'd look into for troubleshooting.
First test:
Most simply, try disconnecting the Nocturn and close the Automap software to see if you can launch your project. This may or may not have an impact.
Second test:
Try launching your project in SAFE Mode. You can do this by launching SONAR first without opening a project. Afterwards, hold down the SHIFT key on your keyboard and launch the project in question. It will ask you if you want to enable or disable plug-ins and go through the list of plug-ins present in the session. Try disabling the .dll I mentioned above. If it still crashes, try disabling the Steven Slate Virtual Channel plug-in altogether. If it still crashes, try disabling all plug-ins. Jot down which method gets you into the project.
Third test:
Have you tried the recommend reset and rescan steps we listed here?

Best regards,
