You can also continue to use your Lightroom Classic software with your Catalogs, in reduced mode. This gives you normal full use of the Library module. So you can still e.g. see your photos' organisation in Collections etc, as well as export or print them, provided you are signed in to this same Adobe Account for which the subscription has lapsed. But until you take up a new subscription, the Develop module and the Map module will be unavailable.
For clarity, this is different from Photoshop. That software will refuse to run at all, once the subscription has ended.
