Cocos2d-x Sprite :: create ("filename.png") returning null

Question

For some reason this has stopped working. He worked the last time I worked on a project, but now it’s not. I double checked that it is spaceCannonTitle.pngincluded in the project. But it throws an exception to the setPosition line, because title_sprite is null.

bool MenuScene::init()
{
    if ( !Layer::init() )
    {
        return false;
    }

    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();

    auto title_sprite = cocos2d::Sprite::create( "spaceCannonTitle.png" );
    title_sprite->setPosition( Point( visibleSize.width / 2 + origin.x, visibleSize.height - title_sprite->getContentSize( ).height ) );

    this->addChild( title_sprite );
    ...
}

EDIT: If I comment on title_sprite, this is not a failure, but I do not see the menu, and I get this error:

libpng error: CgBI: unhandled critical chunk

I found a solution here . Apparently you need to go to "Build Settings" and install Remove Text Metadata From PNG Fileson NO.
