Joomla 3.10.12, JCE Pro 2.9.52, PHP 7.4.33 (yes, I know ...) When I try to edit an article or create a new one, the page doesn't stop loading, and finally there is a timeout. When I change the editor to TinyMCE, CodeMirror, or "None", I can edit articles, and create new ones. With Error Reporting set to "Maximum" I get this message: 
Warning: Cannot declare class \Joomla\CMS\HTML\Helpers\Sidebar, because the name is already in use 
in /www/htdocs/po#####ng.blog/2022-12-22/administrator/components/com_jce/includes/classmap.php on line 46
(domain name slightly obfuscated by #####) --- (I already tried to post this, but after I had clicked on "Submit" it wasn't there, and I wasn't sure whether or not it was sent. So it might be duplicated. Sorry for that.)

Please try JCE Pro 2.9.53 Beta - https://www.joomlacontenteditor.net/downloads/editor/pro/development

Just because you're not paranoid doesn't mean everybody isn't out to get you.

Yes, once the 2.9.53 Beta is installed it is back to working! :-)

I can edit existing articles, and create new ones while JCE Pro is the default editor, and I enable Error Reporting there is no "Warning" anymore.

Thank you very much for the ultrafast help
