M2.3.6: Cannot copy some products when enable Bss_SeoAltText

ISSUE:

We are facing one issue: Once we enable bin/magento module:enable Bss_SeoAltText, we can't copy some products, variable products especially. If the Bss_SeoAltText module is disabled, it works fine. 

SOLUTION:

When you duplicate any products, the image attribute is also duplicated. There will be 2 saves happening. The first time you save the original product, the images will be renamed. The second time you save the copied product, the images will no longer exist (not be renamed) but in the database, the image attribute has not been updated. The error shows the data existing in the database but the images do not exist. 

To temporarily resolve the issue, please edit the file: app/code/Bss/SeoAltText/Helper/File.php as below:

Or download the file attached below to override the current file on your site.
