onKeyPressed animation exception, help

Hey,

I have been trying to learn cocos using VS and C++. Recently, I have encountered an issue while trying to run an animation when a key on the keyboard is pressed. The code:

Vector<SpriteFrame*> frames = getAnimation("player%d.png", 3);
_player = Sprite::createWithSpriteFrame(frames.front());
this->addChild(_player);
_player->setPosition(x, y);

animation = Animation::createWithSpriteFrames(frames, 1.0f / 3);

auto action = RepeatForever::create(Animate::create(animation));
auto eventListener = EventListenerKeyboard::create();

eventListener->onKeyPressed = [&](EventKeyboard::KeyCode keyCode, Event* event) {


	_player->runAction(action);


};

After compiling this code and executing it, I get this error when I press a key:

Exception thrown: write access violation.
this was 0x10400A62.

And VS leads me to this line in CCRef.cpp file

void Ref::retain()
{
CCASSERT(_referenceCount > 0, "reference count should be greater than 0");
++_referenceCount; // <---- this line

Though, if I put the runAction function outside the onKeyPressed lambda, (in the init function for example) everything works fine and the animation executes.

It's probably something quite obvious, but since I am fairly new I hope to get some insight on what is exactly happening behind the scenes and why there is an error, how should I fix it.

Thanks.
