I am using VS 2017 (15.2)...

For unknown reasons I am no longer able to debug my VSIX projects... If I "Start Debugging" the experimental instance comes but then it immediately goes away, and the debugging session ends... If however I "Start Without Debugging" the experimental instance comes up fine... It's only when debugging that the problem occurs... In order to isolate the problem I created a new VSIX project and sure enough it exhibits the same problem... This behavior I described is what usually happens but on occasion the experimental instance will not even launch... Instead I get an error message that looks something like this:

This was all working not too long ago... Anyone have any ideas on what the issue could be??? How to fix??? A workaround??? BTW one of my colleagues found this link: <https://developercommunity.visualstudio.com/content/problem/14382/vs2017-rc-crash-when-debugging-vsix.html>... Unfortunately though the fix provided did not work... Thank you
