Is this related to WP Engine? https://forum.bricksbuilder.io/t/wait-wp-list-table-error-on-wpengine/21201

Thanks @nicomollet , I check two sites of those affected sites and both are not in WP Engine.

Anyway, the fix is easy, we just need to check if this WP_List_Table class exists or not here: https://github.com/wp-media/imagify-plugin/blob/5684433e2a7d126b312de47ed05d21022483374c/inc/classes/class-imagify-files-list-table.php#L3

if it doesn't exist, load the file:

require_once( ABSPATH . 'wp-admin/includes/class-wp-list-table.php' );

it's XS issue, so I'll go and create the PR quickly for it.
