Hang on Startup

[CelestialPanda42]

If SmartCommandArgs window is tabbed (in my case it's part of the output/ symbols etc tab) then on startup it may hang. Was able to pull the following from ActivityLog.xml. Also using VisualAssist and PlasticSCM plugins.

Which exact version of VS are you using? Does this error occur all the time? Did you try to create a new blank project (without SCM)?

Some people write on the internet that running VS as administrator once could fix this exception. Of course not in the context with our extension ;) So maybe give it a try.

Running VS 2017 V.15.6.1.

This error occurs all the time under the following conditions:
Any project, if I double click the .sln file and SmartCmdArgs window was visible/ docked as part of my preferences then this issue occurs.
This issue does not occur if I open VS/ devenv.exe and then File->Open a Project or Solution.
If SmartCmdArgs is enabled in extensions but not a visible window then there is no issue.

Running VS and opening Solutions as Admin does not fix issue.

It's an odd one for sure!
