Program exited with code -11 when using dagon:nuklear

[KrsKonst]

Hello, I'm trying to run a tutorial project from here. And I'm keep getting the "Program exited with code -11" error.
What I have for now:

project structure

<project root>
  assets
    fonts
      DroidSans.ttf
  source
    scenes
      MainMenu
        MainMenu.d
    app.d

//app.d

module main;

import dagon;
import scene;
import scenes.MainMenu;

class MyGame: Game
{
    this(uint windowWidth, uint windowHeight, bool fullscreen, string title, string[] args)
    {
        super(windowWidth, windowHeight, fullscreen, title, args);
        currentScene = New!MainMenu(this);
    }
}

void main(string[] args)
{
    MyGame game = New!MyGame(1280, 720, false, "Dagon test", args);
    game.run();
    Delete(game);
}

//scenes/MainMenu/MainMenu.d

module scenes.MainMenu;

import dagon;
import dagon.ext.nuklear;
import dagon.ext.ftfont;

class MainMenu: Scene {
    Game game;
    FontAsset font;
    NuklearGUI ui;
    Entity uiEntity;

    this(Game game){
        super(game);
        this.game = game;
    }

    override void beforeLoad(){
        font = this.addFontAsset("assets/fonts/DroidSans.ttf", 18);
    }

    override void afterLoad(){
        ui = New!NuklearGUI(eventManager, assetManager);
        ui.addFont(font, 18, ui.localeGlyphRanges);

        uiEntity = addEntityHUD();
        uiEntity.drawable = ui;
        uiEntity.visible = true;

        eventManager.showCursor(true);
    }

    override void onUpdate(Time time){
        if(uiEntity.visible){
            ui.update(time);
            layout();
        }
    }

    void layout(){
        /** TODO: ui elements **/
    }
}

unit tests for dagon:nuklear are fine

I've also tried to change dub.json that way, so it would be more like that

{
	"authors": [
		""
	],
	"dependencies": {
		"dagon": "~master",
		"dagon:ftfont": "~master",
		"dagon:nuklear": "~master"
	},
	"license": "proprietary",
	"name": "untitledspacegame",
	"targetName": "Untitled_space_game"
}

but I'm getting the same error

Thanks in advance for reply.

Also both dub run --build-mode separate and dub run are creating Untitled_space_game file in project root. And when I'm trying to run it, I'm getting

Warning: no "settings.conf" found
Warning: no "input.conf" found
Segmentation fault (core dumped)

[KrsKonst]

And running project binary with gdb tells that the problem is in nk_init for some reason

$ gdb ./Untitled_space_game

Reading symbols from ./Untitled_space_game...

(gdb) run ./Untitled_space_game

I've replicated this on Mint 21.2 (Ubuntu 22.04 LTS). Must be something broken in libnuklear
