Issue description:
I'm getting weird errors while dynamically setting script for a node. Right now, I try to generate a scene randomly. I have a class with a logic which eventually boils down to this:

public virtual Node2D GenerateTileScene(List<Decoration> decorations)
    {
        //first, we place the objects and then look for a spot for player
        scene.SetScript(GD.Weakref(this));
        scene.AddChild(this);
        scenePlacementLogic.PlaceDecorations(decorations);
        scenePlacementLogic.PlaceObject(player);
        return scene;
    }

This configuration gives me this weird Godot error:

Stacktrace:

  at <unknown> <0xffffffff>
munmap_chunk(): invalid pointer

However, if I move the first two lines to the end of the function, everything works:

    {
        //first, we place the objects and then look for a spot for player
        scenePlacementLogic.PlaceDecorations(decorations);
        scenePlacementLogic.PlaceObject(player);
        scene.SetScript(GD.Weakref(this));
        scene.AddChild(this);
        return scene;
    }

I thought it was connected to the fact that I shouldn't set script while the class instance was being busy placing objects on the scene, so I tried CallDeferred() but got the same error.

Please note that the scene object is not in the SceneTree while running this, the scene is only added to the tree once the decorations are set up and the SetScript is called.

Also, I started getting this weird stacktrace while closing Godot window (definitely related to SetScript/WeakRef, because if I close the window before this line is called then no stacktrace is shown):

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

More observations:

If I try to store the generated scene (with added script) to a variable and switch to it it later on, it doesn't work:

if (targetScene !=null)
        {
           CallDeferred("SwitchScene",targetScene);
        }
        
    }

    public void SwitchScene(Node targetScene)
    {
        GD.Print($"Switching to: {targetScene}");
	var currentScene = GetTree().GetCurrentScene();
        GetTree().GetRoot().AddChild(targetScene);
        GetTree().SetCurrentScene(targetScene);
        eventBus.Publish(Address.GameEvents,new SceneChangedEvent(targetScene));
        currentScene.QueueFree();
    }

In the case of the stored scene, the targetScene will always be Null . Same function works perfectly in other cases.

If I try to get NativeInstance or even inspect the scene in VSCode debug console, I get the stacktrace (see below):

Plus, it seems that the game exits abruptly after some time with a similar stacktrace.

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

And another observation - this behavior seems to corrupt .mono folder. If I open Godot itself after the exception (I usually build and run with msbuild via command line), it will close almost instantly. To fix it, I need to delete .mono folder, reopen Godot and run the script from there so that it rebuilds the required files.

For easier testing, could you share a minimal example project to reproduce the bug?

This one generates the exception, just hit the "Start" button.

I don't see the output of exception in Godot console, although Godot does close abruptly. I generally see the output by running

TERM=xterm && cd ~/example && msbuild . /p:Configuration=Tools && godot-mono

and then watching the terminal

@xfactor2000 Consider moving your log outputs into GitHub Gists.

Also, I can't reproduce with the example project because GD.Weakref() does not exist in 3.1 beta 2.

I think Weakref() was moved to Godot.Object.

Can anyone give me an update of the state of this issue on latest master? Specially if the backtrace at the end is still reproducible.

Regarding SetScript, you have to be careful how you use it. You cannot asume the managed object you are calling it on will be usable after that. If previous to the call it had a C# script attached, then it will be disposed. Hence the Parameter ' ptr ' is null errors (which should be change to be an ObjectDisposedException instead).

Doesn't seem to crash anymore in 3.1 beta 6, after changing GD.Weakref() to Godot.Object.WeakRef().
It compiles and runs fine.
