No link template 'canonical' found for the 'paragraph' entity type

Problem/Motivation

I have taken over an older 8.x site and migrated that to 9.2 when I realized that the client had configured a comment type which is attached to paragraph entities. I know this is strange at least. But it causes a crash when going to the comment overview page /admin/content/comment because the commented entities don't have canonical link templates.

Proposed resolution

Check for the canonical link template before creating a url.

    I use comments to comment on paragraphs - on Drupal 8 everything worked fine.
    I have the problem described above after upgrading Drupal from 8.9.20 to 9.5.4 i.e. comment overview page /admin/content/comment is not displayed - error mesage:
    Drupal\Core\Entity\Exception\UndefinedLinkTemplateException: No link template 'canonical' found for the 'paragraph' entity type in Drupal\Core\Entity\EntityBase->toUrl() (line 196 of core/lib/Drupal/Core/Entity/EntityBase.php).
    rdf_comment_storage_load(Array) (Line: 877)

    After update #11 core/modules/comment/src/Form/CommentAdminOverview.php - display new error:
    The website encountered an unexpected error. Please try again later.
    Error: Call to a member function toString() on string in rdf_comment_storage_load() (line 264 of core/modules/rdf/rdf.module).
    rdf_comment_storage_load(Array) (Line: 877)

    I will add that all modules have been updated to the latest versions, including depreciated ones.

    Does anyone have any idea to solve this problem?
