Answer 1

Try this $product->save(); instead of $productRepository->save($product);

Answer 2

I was having same issue while trying to duplicate products in 2.3.3 . The image that has issue was in DB (media gallery table) but physical file was not available and copying of images from old product to new product was not working because of this case.

Solution mentioned in this link worked for me: How can I remove not existing images in magento 2

i created a function based on this suggestion which will delete such images from the database. My function looked as below:

public function deleteOrphanImages()
{
    $mediaDir = $this->fileSystem->getDirectoryWrite(DirectoryList::MEDIA);

    $connection = $this->resourceConnection->getConnection('core_write');

    $tableName = $connection->getTableName('catalog_product_entity_media_gallery');
    $result = $connection->fetchAll('SELECT * FROM ' .$tableName. ' where media_type = "image"');
    foreach ($result as $item) {
        $imagePath = $mediaDir->getAbsolutePath($item['value']);

        if (!$mediaDir->isExist($imagePath)) {
            $sql = "Delete FROM " . $tableName . " Where value_id = " . $item['value_id'];
            $connection->query($sql);
        }
    }

}

I personally did not like using direct SQL to delete from DB but this is something working for me.
