Revit crashes when loading a script with archi-lab and Clockwork nodes

I had the same issue.
I have the following observations:

  1. Using the latest build I was able to get back into my script. Archilab and Rhythym are still giving System.IO.FileLoadException.
  2. I was able to get back into my script after removing all packages from AppData\Roaming\Dynamo\Dynamo Revit\2.0\packages
  3. I was able to get back into my script after removing the library xml manifest file the libraryViewExtension

But after 2 and 3 you can do nothing with dynamo.

My solution is I start with opening the dynamo file which only use the archilab package first then later open the file with both packages then dynamo should not crash.
