Compiling On UE5.4.4 removes BindWidget value

Experiencing an issue I have not seen before with the UMG Designer and widget bindings.

Working in the UUserWidget domain, creating a Widget in the Editor and setting its parent to my widget class, then attempting to Bind my widget as I’ve done many times before and it will wipe the value during compilation.

Property declaration

Add HorizontalBox widget to tree

Assign bound value of Spacer

Now I hit compile… After which my value is just deleted and I’m left with the error below.

Am I experiencing a UE5.4.4 bug? Is it as simple as updating the project to UE5.5?

Note: I’ve also attempted with VisibleDefaultsOnly, BlueprintReadOnly, BindWidgetOptional, all of which are not keeping my value stored.
