I Tried using the GetAllActorsOfClass to get current levelBP reference but it can not save the game.

And I tried others way like GetStreamingLevel and call a interface function but GetStreamingLevel was keeping casting fail the level reference.

Does any good way to Get/Set levelbulueprint variable?

It is possible to create a reference to an actor in your scene. This reference will give you a possibility to access variables.
In case I want to set a variable in whole class of actors I use dispatchers.
