WP 5.3 / Version 5.5.2 PHP fatal error

When starting the scan I get the following error message:

[Sat Nov 30 19:14:45.927017 2019] [php7:error] [pid 17560] [client 79.233.51.216:51712] PHP Fatal error: Uncaught Error: Call to undefined function mb_convert_encoding() in /var/www-server/photo/blog/wp-content/plugins/media-cleaner/core.php:156\nStack trace:\n#0 /var/www-server/photo/blog/wp-content/plugins/media-cleaner/parsers/common.php(83): Meow_WPMC_Core->get_urls_from_html(‘<p>\\nImp…’)\n#1 /var/www-server/photo/blog/wp-includes/class-wp-hook.php(288): MeowApps_WPMC_Parser->scan_post(‘<p>\\nImp…’, ‘5918’)\n#2 /var/www-server/photo/blog/wp-includes/class-wp-hook.php(312): WP_Hook->apply_filters(”, Array)\n#3 /var/www-server/photo/blog/wp-includes/plugin.php(478): WP_Hook->do_action(Array)\n#4 /var/www-server/photo/blog/wp-content/plugins/media-cleaner/engine.php(91): do_action(‘wpmc_scan_post’, ‘<p>\\nImp…’, ‘5918’)\n#5 /var/www-server/photo/blog/wp-content/plugins/media-cleaner/api.php(27): Meow_WPMC_Engine->parse(‘0’, ‘5’, NULL)\n#6 /var/www-server/photo/blog/wp-includes/class-wp-hook.php(288): Meow_WPMC_API->wp_ajax_wpmc_prepare_do(”)\n#7 /var/www-server/photo/blog/wp-includes/class- in /var/www-server/photo/blog/wp-content/plugins/media-cleaner/core.php on line 156, referer: https://photo.m-j-s.net/blog/wp-admin/upload.php?page=media-cleaner

Any idea? Thanks.
