I think we are going to do this in ๐ Update explicit core compatibility in supported releases Fixed so I am marking this as a duplicate.
Since the changes made in https://www.drupal.org/project/webform/issues/3265557 โ Webform is not compatible with Drupal versions below 9.3. @Berdir flagged the core version requirement change in the linked issue (#13), but it appears to have been missed when the change was deployed.
Install Webform 6.1.x on a Drupal version less than 9.3 and visit "admin/structure/webform/submissions/manage". The error is โSymfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "file_url_generator". Did you mean this: "url_generator"?โ
Update the core version requirement to Drupal 9.3.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
