Adding it wouldn’t change anything. Could you confirm it prints? You should be seeing a blue Hello in the upper left corner when the game Begins.
It’s in the "GameHUD blueprint
Widgets do not have Begin Play. Is this in a HUD class by any chance?
When you open this blueprint, what do you see in the upper right corner? Parent Class: ???
Where would I get the hierarchy?
In the widget designer, where you designed the widget, added the text block and so on.
