This was my issue.
I pulled up a project I am working on and to my surprise the tracks I have the AbbeyRoad Plates are redlining as
if I am feeding it an extremely hot signal and the project won't play. When I trun off the plugin the project plays fine. I save and close and get a crash dump error.
( Module C:\programfiles(86) Waves\Plug-insV9\ARPlate/bundle\content\win64\ARPlates.dll)
Then there is an exception code c0000005 and so on. I uninstall Waves and re-installed to no avail.
This issue is with Sonar only as the Abbeyroad Plate and all my other plugins are working fine with no issue in studio One and Mixbus. I'm not sure what to try at this point. I would assume if the plugin is faulty it wouldn't work in any DAW.
