Unreal Engine Issues and Bug Tracker (UE-113948)

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

Create a First Person Template project
In the FirstPersonCharacter Blueprint, add an AIPerceptionStimuliSource component
In the details panel on the component, set Auto Register As Source to true
Add AISense_Sight to the Register as source for senses array
Create a new Pawn Blueprint named AI_Pawn
Add an AIPerception component to the AI_Pawn BP
Add a SetSenseEnabled node to the event graph of AI_Pawn
Connect it to the Event BeginPlay node
Select Sight as the sense class on the SetSenseEnabled node
Set Enabled to true on the SetSense Enabled node
Add the AI_Pawn to the map
Press the play button

RESULT:

**The editor crashes with Assertion Failed: SenseConfig

EXPECTED:

The editor doesn't crash when using the SetSenseEnabled node
