Having a CreateWidget blueprint node with certain UserWidget classes causes the engine to crash intermittently in Standalone.
The blueprint node isn’t even hooked up to anything, just having it in the GameInstance blueprint causes the game to crash.
This also happens if there is a variable in the GameInstance blueprint with a UserWidget type.
This only happens on some UMG widgets, we’ve tried a few of the widgets we’ve created and some actually work fine.
One of the symptoms of this bug is that other UI widgets will turn black on in-game menus.
The crash seems to occur under the following conditions in standalone:
- When a unrelated in-game widget is created
- When a button is pressed
- When the standalone instance is started
