Reload scene after changes C#

Hello to all,

First of all I'm new in GoDot so I make some simple examples in order to see how godot works.

I create my scene from Editor, so using script in c# I want to change Node from current parent, add to another parent in the same scene and reload a scene again in order to see the result directly.

I remove child from previous parent and add to the new parent, but I could not see the result in the current scene after play from Editor. Then I found that I have to call reload scene but I guess it stuck somewhere and the scene cannot be loaded (noting happened after Play from Editor - black screen and it looks like stuck in some loop). Can you please help me what can be problem here that I cannot reload my scene with new changes.

In addition part of my test code:

Node currScene = GetTree().CurrentScene;

    if (currScene == null)
    {
        GetTree().CurrentScene = (Spatial)currProjectScene.Instance();
        GD.Print("No Current scene set!");
    }
    else
    {
        GD.Print(" Current scene is set!");
        GetTree().ReloadCurrentScene();
    }

Thanks a lot for help,
Ivi
