Each time there is a major update in the OS, the version of Photos adds new stuff that can't be interpreted by Photos from a previous version. An older version of Photos just doesn't have the slots for new pegs to fit into. So the answer is, unfortunately, you can't work with a Monterey (for instance) Photos Library in Catalina. You need either to upgrade to the system you last used to load the library, or you need to find an upgraded Mac somewhere and export all the pictures.

If your Photos Library is in iCloud, you can downgrade your Photos Library to Catalina like this: Rebuilding a Photos Library by downloading a new Copy from iCloud - Apple Community
You can't. Photos libraries are not backward compatible. You'll have to update your system to the same system that the library came from.
