INSTALL last version

I’m on my Windows desktop now, so can share a screenshot:

What you are looking for are the data.db-pre-... and library.db-pre-... files.
Rename data.db to data.db-4.6, library.db to library.db-4.6, for example (or, if you are brave, you can delete them right now). Then rename (or copy) the ...-pre-... database files accordingly.

The ...-snp-... files are also backups, made at the indicated point in time (data.db-snp-20230922191804 would be a backup of data.db, made on 22 September 2023 at 19:18:04. You can also use those to restore previous versions.
