Replace this below code in your file :

protected $collectionFactory;

public function __construct(
    \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $collectionFactory
) {
    $this->collectionFactory = $collectionFactory;
}

public function getProduct($product_id){
    try{
        $product = $this->collectionFactory->create()
            ->addAttributeToSelect('*')
            ->addAttributeToFilter('entity_id', ['eq' => $product_id])
            ->addWebsiteFilter('your_website_id');
        return $product;
    }catch (\Exception $ex){
        $this->log($ex->getMessage());
    }
}

After that, you can get count of collection :

$productId = "10";
if(count($block->getProduct($productId)) > 0)
{
   echo "Product Exist";
} else {
   echo "Product Not Exist";
}

Remove generated and clean cache.

The getProduct function takes the store id and the product id as parameter and it runs the product model for that specific store.

And the getProductCollection function takes store id as parameter and returns the product collection for that specific store view.

public function __construct(
    ...
    \Magento\Catalog\Model\ProductFactory $productFactory,
    ...
) {
    ...
    $this->productFactory = $productFactory;
    ...
}

public function getProduct($storeId, $productId) {
    $product = $this->productFactory->create()
                            ->setStoreId($storeId)
                            ->load($productId);
    return $product;
}

public function getProductCollection($storeId) {
    $productCollection = $this->productFactory->create()
                                    ->setStoreId($storeId)
                                    ->getCollection()
                                    ->addAttributeToSelect('*');
    return $productCollection;
}
