Hi,

At JCE Control Panel page, I see the following:

Warning: Cannot declare class \Joomla\CMS\HTML\Helpers\Sidebar, because the name is already in use in public_html/administrator/components/com_jce/includes/classmap.php on line 46

At JCE Editor Profiles for Default settings page,
I see following error whenever I make a change and click on save.

An error has occurred.
0 Class "Joomla\CMS\Form\Field\ListField" not found


I am using Joomla! 3.10.12
PHP version: 8.0.30
JCE Editor Pro 2.9.51
