AppHangB1 is not a crash in common sense, it is "stuck". So, processor/RAM/SSD are 99.99% are not the reason.
An application can stuck 2 ways:
1) internally (endless loop) in Sonar, any VST, any Control surface plug-in
2) communicating with the system (audio/video/MIDI drivers)
I would try to first reproduce the bug with huge ASIO buffers. Note that the reason still can be in Sonar/plug-in in case you no longer has hangs then. Next step is to disable ALL audio devices.
If it still stuck, you have to find the problematic software component. Sonar will not help you there, just try to either remove some plug-ins (from the project) or better start from empty project and add components, heavy testing every time. In any case, remove ALL Control surfaces from the list and uncheck all MIDI devices. Final target is to hang Sonar with the smallest possible components/vsts you want to use.
