Description

REGRESSION Was not able to reproduce this in 4.24

Crash occurs when the user attempts to run a networking PIE session in a world containing an EQSTestingPawn actor.

I was not able to reproduce this in 4.26.

Steps to Reproduce
  1. Open any project in editor.
  2. In Editor Preferences > Experimental, enable Environment Query System
  3. Create a blueprint based on EQSTestingPawn and add it to the level.
  4. Click the dropdown next to the play button and set Number of Players to 2, and Net Mode as Play as Listen Server.
  5. Play in viewport.

RESULT
