Editors crashes on opening a series of blueprints

Everything used to be fine and suddenly the editor crashed and since then we can not get a stable version of all our blueprints compiled. We are in a very crucial stage with the game and have been trying to figure this out since a few days.
I have included the crash report and one of the affected blueprints.
Would be great if someone could look into this.
