Description

This is a regression. Tested in //UE4/Release-4.27 CL#18319896

Fatal Error when setting S RGB to true on a Texture 2D from a Render Target Create Static Texture Editor Only node.

Steps to Reproduce
  1. Create or open any project
  2. Create a new Actor Blueprint(link in comments)
    1. Off the 'Event BeginPlay' node create a 'Create Render Target 2D' node
    2. Drag off the return value to create a 'Draw Material to Render Target' node
    3. Promote Material input pin to a variable
    4. Drag off the 'Create Render Target 2D' node's return value and create a 'Render Target Create Static Texture Editor Only' node that is placed after the 'Draw Material to Render Target' node
    5. Off the 'Render Target Create Static Texture Editor Only' node's Return Value output pin then create a 'Set S RGB' node
    6. Set it to true
    7. Compile, save, and close the blueprint
  3. Place the Blueprint Actor in the level
  4. Play in Editor

Expected Results:
No Crash when the SRGB is set to true

Actual Results:
Editor Crashes with a fatal error:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000071a690e0000

Work Around:
Use an Editor Utilities Blueprint instead of a regular BP and then use the SetEditorProperty node to set the SRGB property of the texture.
