C# Godot / Compiler crashes when trying to add nodes via code

shinXdxd

public class Block : StaticBody2D
{
    private BlockType type {get;}
    // private Sprite sprite = new Sprite(); // this line causes a crash

    public Block(BlockType type, Vector2 position)
    {
        this.type = type;
        this.Position = position;
       // crashes somewhere on the next lines
        Sprite sprite = new Sprite();
        sprite.Texture = (Texture) GD.Load("res://assets/earth.png");
        this.AddChild(sprite);

    }

I'm trying to add nodes to a scene via Code. But the code crashes when trying to create objects of some classes like sprites. It also crashes if I want to add another Object as a class-member.

I don't know why the compiler (or godot) crashes on something trivial like Sprite sprite = new Sprite() How can I do this so I can compile my project?

Should that line be:

var sprite = new Sprite();

Sorry I use GDScript, but I did a quick search and I think that should work.

I tried the code with GDScript and there it works, but If I do the same in C# the whole IDE crashes as soon as I try to compile. var sprite = new Sprite(); is actually the same as Sprite sprite = new Sprite(); at least with this simple line of code. This is the output i got (I'm using linux) :

I understand what the error is staying. It looks like your Block class needs a default constructor (with no parameters/arguments). For example, try something like this:

public class Block : StaticBody2D
{
    private BlockType type {get;}
    // private Sprite sprite = new Sprite(); // this line causes a crash
   public Block() 
   {
   }
    public Create(BlockType type, Vector2 position)
    {
        this.type = type;
        this.Position = position;
       // crashes somewhere on the next lines
        Sprite sprite = new Sprite();
        sprite.Texture = (Texture) GD.Load("res://assets/earth.png");
        this.AddChild(sprite);
    }

Thank you for your help. I went once again through the Your first game tutorial and made it with like the mob spawning with a packed scene. Now it's working.
