Editor Crashes When a Component and Actor Implement Two Interfaces

The editor crashes if you implement two blueprint interfaces in an actor blueprint, and then an actor component blueprint. These interfaces must have at least one function that returns a value. The crash occurs only after restarting the editor, and then opening the actor blueprint that implements the two interfaces.

Occurs in 4.8.3, 4.9.2, 4.10 Preview, and Main CL 2731616.

1. Open Editor
2. Create two blueprint interfaces
3. In each, ensure that there is a function that returns a value
4. Create an Actor Blueprint that implements both interfaces
5. Create an ActorComponent Blueprint that implements both interfaces.
6. Add the component to the actor blueprint
7. Restart the editor and attempt to open the actor blueprint

Result: Editor crashes while trying to open the actor blueprint
