Automatic backup fails with PHP 8

Hi there,

When I try to backup my sites via scheduled backup it throws the following message when I use PHP 8 on this site:

PHP Fatal error occurred: Uncaught ValueError: fread(): Argument #2 ($length) must be greater than 0 in /absolute/path/wp-content/plugins/iwp-client/pclzip.class.php:3443 Stack trace: #0 /absolute/path/wp-content/plugins/iwp-client/pclzip.class.php(3443): fread(Resource id #11344, 0) #1 /absolute/path/wp-content/plugins/iwp-client/pclzip.class.php(3236): IWPPclZip->privAddFile(Array, Array, Array) #2 /absolute/path/wp-content/plugins/iwp-client/pclzip.class.php(2967): IWPPclZip->privAddFileList(Array, Array, Array) #3 /absolute/path/wp-content/plugins/iwp-client/pclzip.class.php(1023): IWPPclZip->privAdd(Array, Array, Array) #4 /absolute/path/wp-content/plugins/iwp-client/backup.class.singlecall.php(888): IWPPclZip->add(Array, 77003, '/absolute/path/...', 77999, Array, 77020, 1) #5 /absolute/path/wp-content/plugins/iwp-client/backup.class.singlecall.php(757): IWP_MMB_Backup_Singlecall->fail_safe_pcl_files('fb6fca68a2c9b09...', '/absolute/path/...', Array, Array, '1', NULL, Array, Array) #6 /absolute/path/wp-content/plugins/iwp-client/backup.class.singlecall.php(327): IWP_MMB_Backup_Singlecall->backup_files_alone('fb6fca68a2c9b09...', '/absolute/path/...', Array, Array, '-0', 50, Array) #7 /absolute/path/wp-content/plugins/iwp-client/backup.class.singlecall.php(180): IWP_MMB_Backup_Singlecall->backup(Array, 'fb6fca68a2c9b09...') #8 /absolute/path/wp-content/plugins/iwp-client/init.php(875): IWP_MMB_Backup_Singlecall->set_backup_task(Array) #9 /absolute/path/wp-content/plugins/iwp-client/core.class.php(300): iwp_mmb_run_task_now(Array) #10 /absolute/path/wp-includes/class-wp-hook.php(292): IWP_MMB_Core->iwp_mmb_remote_action('') #11 /absolute/path/wp-includes/class-wp-hook.php(316): WP_Hook->apply_filters(NULL, Array) #12 /absolute/path/wp-includes/plugin.php(484): WP_Hook->do_action(Array) #13 /absolute/path/wp-settings.php(560): do_action('init') #14 /absolute/path/wp-config.php(101): require_once('/absolute/path/...') #15 /absolute/path/wp-load.php(37): require_once('/absolute/path/...') #16 {main} thrown in /absolute/path/wp-content/plugins/iwp-client/pclzip.class.php on line 3443.

When I run the backup manually via IWP panel, it works fine.

Any ideas?
