Your import stops and displays this error:
Fatal error: Uncaught exception 'PrestaShopException' with message 'Property Tag->name length (44) must be between 0 and 32'
This means that a tag name in your import file uses 44 characters when the limit is 32.
You therefore need to download the corresponding TODO file to modify the concerned tag.
Save the changes, reload the TODO file and start the import process again.
