I’m making a package for Marketplace and I need to code an editor for it. I am using EditorUtilityWidget for this editor. But when I create a new widget on the EditorUtilityWidget and try to use a button on it, it doesn’t work. The problem is not that it doesn’t work, the problem is that it sometimes works. 
I don’t know something? I was making this package in UE5.1 before, but a widget literally died. Even the Event Construct was not working even though I saw the widget. Indeed, I have 8 years of unreal experience and even Event Construct was not working. So I’m not the problem.
Afterwards, I went back to UE4.26 and the problem partially persists. Thanks.
When you say “create a new widget on the EditorUtilityWidget”, do you mean dynamically instantiating a widget that’s childed to something on the utility widget, or do you mean you’ve made a second widget and dragged the blueprint into the utility widget?
