Failed to open stream: /helper.php in AcyMailing Essential 10 +Joomla 5

Hi,
I have these warnings on top of page when I edit an article in joomla :

Warning: include_once(/homepages/.../htdocs/.../administrator/components/com_acymailing/helpers/helper.php): Failed to open stream: No such file or directory in /homepages/.../htdocs/.../plugins/editors/acyeditor/acyeditor.php on line 19
Warning: include_once(): Failed opening '/homepages/.../htdocs/.../administrator/components/com_acymailing/helpers/helper.php' for inclusion (include_path='.:/usr/lib/php8.3') in /homepages/.../htdocs/
.../plugins/editors/acyeditor/acyeditor.php on line 19

Looking on the server, I see that :

I have a folder /administrator/components/com_acym/ and not /administrator/components/com_acymailing/
the last update date of file acyeditor.php is on 07/2023

Is somebody knowing this problem ? And how to resolve it ?
Thanks !
