"Cast to" not working

I’m using UE 4.10.2 and I’m trying to cast from a pawn to another, but when I do, the node doesn’t show up. Sometimes I can restart the editor and the node will appear, but when I run the game in a standalone editor or launch the game, it will become unresponsive, up until I remove the “Cast to” node. Is this a possible issue with the editor? I tried commenting and received this crash log:

Now I can’t even open the editor because it gets stuck initializing at 72%

Any help would be greatly appreciated.
