Fatal error whenever I try to use the plugin

I get a PHP fatal error whenever I try to use the plugin.

Batch Downloader version: 13.a
Piwigo version: 13.8.0
PHP version:

$ php --version
PHP 7.4.33 (cli) (built: Sep  4 2023 08:11:54) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.33, Copyright (c), by Zend Technologies

Full error:

Fatal error: Uncaught ValueError: fread(): Argument #2 ($length) must be greater than 0 in /var/www/piwigo/admin/include/pclzip.lib.php:2674 Stack trace: #0 /var/www/piwigo/admin/include/pclzip.lib.php(2674): fread() #1 /var/www/piwigo/admin/include/pclzip.lib.php(2504): PclZip->privAddFile() #2 /var/www/piwigo/admin/include/pclzip.lib.php(2406): PclZip->privAddFileList() #3 /var/www/piwigo/admin/include/pclzip.lib.php(2141): PclZip->privAddList() #4 /var/www/piwigo/admin/include/pclzip.lib.php(409): PclZip->privCreate() #5 /var/www/piwigo/plugins/BatchDownloader/include/BatchDownloader.class.php(998): PclZip->create() #6 /var/www/piwigo/plugins/BatchDownloader/include/BatchDownloader.class.php(516): myZip->__construct() #7 /var/www/piwigo/plugins/BatchDownloader/include/events.inc.php(102): BatchDownloader->createNextArchive() #8 /var/www/piwigo/include/functions_plugins.inc.php(264): batch_download_index_button() #9 /var/www/piwigo/index.php(351): trigger_notify() #10 {main} thrown in /var/www/piwigo/admin/include/pclzip.lib.php on line 2674

Haven't found anything similar online. Any help would be appreciated.

Hmm, one year has passed and no one has commented on this error.

I have the same error, but the plugin version I have installed is 14.5
That makes me think the developer knows about it and this is a problem with only some users, not all.

So what is the fix? Did you ever find a solution?

I may have found a solution for this problem. I noticed that this plugin was complaining that it could not find ZipArchive on my webhost, so it will use PclZip. I went into my host's cPanel and went to
Software > Select PHP version
On that page under "Z" I enabled the checkbox for Zip

After that the error showing up in this plugin's setting page went away. I was then able to download the album as a zip file using the cloud button on my photo album's page.

Notes:

1. Also went away was the error related to undefined array and this one:
   Fatal error: Uncaught ValueError: fread(): Argument Contourne l'interdiction de télécharger des photos en les ajoutant à une collection #2 ($length) must be greater than 0.

2. This error is still there, if "Photo size choices" is set to One size = Original
   Downloader Warning: Undefined array key "SIZE_INFO" in file.init_zip.tpl.php on line 153
