So there is action to pause scene and go to another scene
And there is another action to go back to previously paused scene
Just add action and type scene in search bar
And pick ones you need
it will only restart the scene
It should not restart scene
But if your problem is saving related you can always revert to using saving and loading
it is not about saving anything either
If your idea is to have scene in same state that you had it before leaving to other scene and after coming back to initial scene then it is
If scene resets for you when using pause scene action
Then your workaround would be to save everything in scene you leaving and loading it when you are coming back
