I've been working on a few projects tonight using Slate Digital's new VCC 2.0 & every time I close X3 I get this type of crash:

Problem signature:
  Problem Event Name:    APPCRASH
  Application Name:    SONARPDR.exe
  Application Version:    20.0.5.352
  Application Timestamp:    5320c501
  Fault Module Name:    InnerProcessDictionary_x64.dll
  Fault Module Version:    1.3.0.65300

I've never heard of or ever remember having a crash of a InnerProcessDictionary_x64.dll
Any one else, any idea what it means?

Did you do a full VST reset and rescan? 
 
I'd try that first.
 
And then reboot X3 (not the computer).

I did a reboot, after installing the plugins scanning pop-up showing them as new.
I was using them in projects for a few hours. Only when closing it crashed.
I'll try a total re-scan though. Is that what the dictionary.dll is all about?
 

Any Waves plug-ins in these projects?

Yep

I believe InnerProcessDictionary_x64.dll came from Waves. Maybe located in "C:\ProgramData\Waves Audio\Modules." Don't have Waves or Slate plug-ins here to test through.

Thanks for the info.
I just upgraded Waves too so that could be the problem. I'll keep that in mind if it keeps crashing & contact them.

I only have a rudimentary project going right now with VCC 2.0 in it.  
 
What I'm seeing is that if VCC is set to Group 1, when I close the project and then open it again, the Link button is off and the Input and Output controls are set to -18.  I can use Group 2 and 3 ok.  I haven't tried any other groups.
 
BTW, no crashes with this little test project and I have Waves, UAD and Slate VTM in it.

ce

Also a good reason why you should do a VST Reset-Rescan.  I always have problems with a new Waves install if I forget to do this.
