The stock Content view in a Drupal 9 install is returning a 404 when accessing /admin/content.
We added two contextual filters to this View that are ignored if you are an Admin (passes "all" value).
If you navigate to /admin/content/node, you get the View. But admin/content is a 404, and other sites we have work fine (no filters on the View). I see someone changed the path in the View, but changing it back causes it to ping pong between 404 and the View. Is there something else that could cause this?
