For anyone in need of the “Get Root Widget” function in blueprints, especially in the dynamic widget tree where assigning manually isn’t practical, here’s a recursive function inspired by “BDC_Patrick :de::uk::us:” from the Discord community.
I have tested it. Started from Image. Got the CanvasPanel. Not the Top “CustomUserWidget” as I expected. But this might be handy for you.

In case of the image not loaded properly:

UUserWidget* FindRootWidget(UUserWidget* CurrentWidget)
{
    if(!IsValid(CurrentWidget->GetParent())){
        return CurrentWidget;
    }
    return FindRootWidget(CurrentWidget->GetParent());
}
