I'm using the Media module, but I noticed there isn't a path like /media/%id where I can see the media and its fields.
The only path available seems to be media/%id/edit and media/%id/delete.
On Drupal 8, it was possible to access a media page. What's wrong?
This was an announced change that released in Drupal 8.7.0—"Media items no longer available at /media/{id}". The change added a new setting to enable the "id" route and turned it on for existing sites. New sites must have the setting enabled at /admin/config/media/media-settings.
Steps: To enable this '/media/%id' path:: In Drupal9/10
Enable the 'Media' module and then go to this page: your_site_url/admin/config/media/media-settings
Enable this checkbox 'Standalone media URL'
Additonal info:
#1: Basically this route '/media/%id' disabled by core.
#2: May be in your case module 'Media' enabled, you just need to enable this checkbox 'Standalone media URL' and save the form.
