 * Hello.
 * PHP 8.5.5, WP 6.9.4, WEB Server IIS, Third-party plugins are disabled.
 * I use the plugin (ver. 2.2) with the “Automatically convert images while uploading”
   setting disabled, I add an image in jpg format through the media library, then
   I start the conversion to WebP from the media library (regardless of the library
   used), all image files are successfully replaced with the new format, but at 
   the same time the following warning appears in the PHP log: Undefined array key“
   original_image” in …….\wp-content\plugins\webp-conversion\webp-conversion.php
   on line 1159
 * The same warning appears when running “Restore to Original for Selected”. And
   nothing happens, even though a backup file is being created in the webpc-backup
   folder.
 * Also, this file is not deleted (but without error output to the log) when starting“
   Remove Original from Selected”.
