Magento2: Could not save product "330664" with position 0 to category 3567

https://github.com/magento/magento2/issues/8970

The error is from the CategoryLinkRepository File from module-catalog which handles the save functionality. Check your exception log for more details, which tells you exactly why you couldn't save the product. Hope am pointing you to the right direction. Check also deleteByIds method, it can be the potential cause of this issue.

/**
     * {@inheritdoc}
     */
    public function deleteByIds($categoryId, $sku)
    {
        $category = $this->categoryRepository->get($categoryId);
        $product = $this->productRepository->get($sku);
        $productPositions = $category->getProductsPosition();

        $productID = $product->getId();
        if (!isset($productPositions[$productID])) {
            throw new InputException(__('Category does not contain specified product'));
        }
        $backupPosition = $productPositions[$productID];
        unset($productPositions[$productID]);

        $category->setPostedProducts($productPositions);
        try {
            $category->save();
        } catch (\Exception $e) {
            throw new CouldNotSaveException(
                __(
                    'Could not save product "%product" with position %position to category %category',
                    [
                        "product" => $product->getId(),
                        "position" => $backupPosition,
                        "category" => $category->getId()
                    ]
                ),
                $e
            );
        }
        return true;
    }

magento\vendor\magento\module-catalog\Model\CategoryLinkRepository.php

/**

        $productPositions[$product->getId()] = $productLink->getPosition();
