尝试将向量分配给向量

我有一个函数可以在此处返回对象指针的向量:

std::vector<std::shared_ptr<Object>> STile::ReadFile(const std::string filePath)
{
    std::ifstream infile(workDir.Get() + filePath);
    Tile tile;

    std::vector<std::shared_ptr<Object>> tileObjects;

    while (infile >> tile.x >> tile.y >> tile.tileID)
    {
        std::shared_ptr<Object> tileObject;
        auto sprite = tileObject->addComponent<CSprite>();
        sprite->SetTextureAllocator(&textureAllocator);
        sprite->Load(workDir.Get() + "blocks.png");
        sprite->SetTextureRect(0, 0, 16, 16);
        tileObject->transform->setPosition(tile.x, tile.y);

        tileObjects.emplace_back(tileObject);
    }

    return tileObjects;
}

现在我正在尝试将返回的向量分配给此处的新向量:

std::vector<std::shared_ptr<Object>> levelTiles = tileSystem.ReadFile("cord.txt");

结果是异常“抛出异常:读取访问冲突”。有什么建议吗?感谢您的帮助:)
