Answer 1

I think you miss the trick, use quotation mark in href

<a href="<?php echo $_item->getProduct()->getProductUrl() ?>">

I hope this will help

Answer 2

Try this:

<?php $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
      $product = $objectManager->create('Magento\Catalog\Model\Product')->load($_item- 
                  >getProduct()->getId());
       $product_url = $product->getProductUrl(); ?>
