Menu widget doesn't show up when packaging my project

Hi everyone, I am beginner with Unreal and sorry for my bad english. Yesterday I finished my project but when I package my project the menu widget doesn’t show up.
This is my level blueprint.

please help me

If you’re doing this in the level blueprint, there could be a chance that the player controller has not been initialized yet in the packaged version when the create widget node is called. Instead try calling the Create Widget node from your player controller.

it doesn’t work . I tried to create the pause menu and I discovered that the pause widget doesn’t show up too like all the widgets are disabled
