CategoryTreeNodeKey does not exist error

Permalink
Hello,

Whilst trying to access a website on 5.7.5.9 I am getting the following error - Class \Concrete\Core\Permission\Key\CategoryTreeNodeKey does not exist

I can't find anything on the web about this and there also isn't even a \Concrete\Core folder for this file to be in.

Any help would be greatly appreciated.

The 'Core' folder is represented by the 'src' folder.
There is no CategoryTreeNodeKey.php file but there is a TopicCategoryTreeNodeKey.php file

I removed the database and re-added it from a backup earlier in the month and that seems to have brought the website back.
