Opening a blueprint, UE4 becomes responsive

I finished up working last night, was only working on one blueprint. I had compiled and saved the blueprint just fine although it was reporting runaway loop detection warnings.

When I attempt to open that same blueprint today, nothing opens, and the task-bar shows empty when I hover over the blueprint editor that should be there, then UE4 becomes unresponsive and has to be closed via the task manager.
