It seems like it must using cast like below :

UMyUserWidger* MyUserWidget = Cast( ??? );

But I don’t know how to get UMyUserWidget Object which must pass to Cast function parameter. HELP please.

You need to have a UUserWidget Object, you can get it when you create the widget using CreateWidget.
For example:

UMyUserWidget* MyWidget = CreateWidget<UMyUserWidget>(this, WidgetClass);

Or you can create a generic UUserWidget object with CreateWidget and then cast it to your class.
WidgetClass in the example must be a

TSubClassOf < UMyUserWidget >
