Editor Crashes when opening a blueprint

Currently using UE 4.6.1. Originally the editor was crashing on startup but I was able to modify the DefaultEngine.ini file so that it wasn’t referencing the level and game mode I had created. I saw a similar post that had the same errors that were popping up in my logs. It yielded some great information on where to find out which blueprint is the culprit, but not exactly how to fix it short of starting the project over.

I have a Widget Blueprint that I made which I use throughout other Widget Blueprints. If I do not open this widget first before opening up other widgets or blueprints that even remotely reference it, the editor crashes, just like paradoc mentions in the answers section of the other post.

I have gone and created a new widget to be used that does the same exact thing (no copy and paste used to prevent spreading possible “corruption”) but has a different name in the editor. After replacing the old widget with the new widget, I am still running in to the same problem, which leads me to believe there is something wrong with the only script I have running in it:

or it has something to do with the way other blueprints are interacting with this one. Forgive me for not spamming you with images of that. Previous versions of the files don’t work. As it stands I’m going to try another workaround but it seems there are enough people with similar experiences and yet there is no clear answer other than us coming to a consensus and saying, “Start from scratch again.” Is there a fix for this coming in a future engine build or do we even know what is causing this problem?

For the record removing the StartDrag Interface function does nothing but removing everything in between the input and output nodes removes all errors everywhere in my project and does not cause it to crash on startup anymore.
