Error after update

Hello Fatima,

I am having some difficulties trying to reproduce the issue. I installed on 12.1.0 and upgraded to 12.4.2 but did not encounter such issue.

Some questions:
- Did you already try a cache clear after the update?
- If you use drush "drush core:route" you are missing the route?
- The route name itself is coming from the view views.view.posts.yaml which is located in social_post. Do you have the file?
- If you get the config "drush cget views.view.posts" do you have the "view.posts.page_admin_content_posts"?

If not you can do a manually import of the config by using the following command
cat html/profiles/contrib/social/modules/social_features/social_post/config/install/views.view.posts.yml | drush cset -y --input-format=yaml views.view.posts ? -
Double check that the "cat" command is actually working as your installation may differ a bit with paths.

For now all I can offer are these manual steps to fix your issue until there are testing steps to reproduce the issue itself.

I encountered the issue once, which seemed to stem from a cache problem. It occurred while I was attempting to reproduce a different issue. The problem arose when I ran 'drush updb' without clearing the cache.
