I had the same problem in my desktop machine after formatting and reinstalling Sonar X3 PE and CWbB. Windows Event Viewer showed that the cause of crashing was in path C:\Program Files\Cakewalk\Vstplugins\BREVERB SONAR\BREVERB 2 Cakewalk-64.dll. It's date was 28.11.2012, size 5544 kb.
Luckily I had in my laptop wellfunctioning CWbB, and I digged from there the same named plugin file dated 8.11.2018, size 5947 kb to replace the file. And Voila! No crashes anymore. I just don't know what I would have done if I didn't have my laptop as reserve...
Where one would get replacing Breverb 2 plugin - except from Overloud, costing 89 dollars?
