Fatal error on the site

Hello,
I’ve just received an email from WordPress with this:
“WordPress has a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.
In this case, WordPress caught an error with one of your plugins, Comment Edit Core.”
And, further down the text:
“Error Details
An error of type E_ERROR was caused in line 873 of the file /web/htdocs/WEBSITE-URL/home/wp-content/plugins/simple-comment-editing/simple-comment-editing.php. Error message: Uncaught Error: Class ‘DLXPlugins\CommentEditLite\Admin\Admin_Settings’ not found in /web/htdocs/WEBSITE-URL/home/wp-content/plugins/simple-comment-editing/simple-comment-editing.php:873″
Now I can’t login to my admin page. When I try, it just tells me “There has been a critical error on this website. Please check your site admin email inbox for instructions.”
