Enable HDR Display Output on Game User Settings Crashes UE4 (UE-60508)

Issue has been filed: https://issues.unrealengine.com/issue/UE-60508

Expected Behavior: HDR should be enabled with no crash.
Actual Behavior: Enabling HDR using Game User Settings in Blueprint crashes the application.
Reproduction Steps:

  1. Create a new Project: Blank Blueprint, Desktop, Max Quality, No Starter Content
  2. Create a new Widget Blueprint, in this widget blueprint:
  3. Create a Button (and optionally text for the button)
  4. Link up the On Clicked event of the button with blueprint
  • [Event On Clicked]
  • [Get Game User Settings]
  • [Enable HDR Display Output] (Target = Get Game User Settings, Enable = True)
  • Compile, Save, Close
  1. World Settings → Game Mode → GameMode Override → [+] (Create New)
  2. World Settings → Game Mode → Selected GameMode → Player Controller Class → [+] (Create New)
  • [Event BeginPlay]
  • [Create Widget] (Class = above defined Widget)
  • [Add To Viewport] (Target = Create Widget)
  • [Set Input Mode UI Only] (Player Controller = Reference To Self, In Widget to Focus = Create Widget)
  • [Set Keyboard Focus] (Target = Create Widget)
  • [Set Show Mouse Cursor] (Show Mouse Cursor = True)
  1. Save All
  2. Play in Standalone so you don’t crash the editor too.
