Description

When adding the SetSenseEnabled node to a Pawn and controlling another pawn that has an AIPerceptionStiumuliSource, the editor crashes. I tested using other senses such as Hearing and the crash occurred regardless. After disconnecting or deleting the SetSenseEnabled node, the crash no longer occurred.

Tested in //UE4/Release-4.25 @ CL 14469661 and this also occurred, so NOT marking as a Regression.

Steps to Reproduce
  1. Create a First Person Template project
  2. In the FirstPersonCharacter Blueprint, add an AIPerceptionStimuliSource component
  3. In the details panel on the component, set Auto Register As Source to true
  4. Add AISense_Sight to the Register as source for senses array
  5. Create a new Pawn Blueprint named AI_Pawn
  6. Add an AIPerception component to the AI_Pawn BP
  7. Add a SetSenseEnabled node to the event graph of AI_Pawn
  8. Connect it to the Event BeginPlay node
  9. Select Sight as the sense class on the SetSenseEnabled node
  10. Set Enabled to true on the SetSense Enabled node
  11. Add the AI_Pawn to the map
  12. Press the play button

RESULT:

**The editor crashes with Assertion Failed: SenseConfig

EXPECTED:

The editor doesn't crash when using the SetSenseEnabled node
