Answer 1

You didn't inject storeManager in construct. Add like this in your construct :

protected $storeManager;

public function __construct(
    .....
    \Magento\Store\Model\StoreManagerInterface $storeManager,
    .....
) {
    $this->storeManager = $storeManager;
}

Now remove generated and clean cache.
