unable to open old aperture library with photos Ventura os

1. Get it off the NAS. Aperture (and iPhoto and Photos) libraries need to be stored on a disk formatted Mac OS Extended (Journaled) or apfs, and directly connected to your Mac, not on a network share. Storing it on an inappropriately formatted disk can cause silent corruption.
2. Since Ventura, you can't open an Aperture library, only import from it using the File -> Import command. Try this after you've moved the library to a correctly formatted disk.

If you have a lot of organizational effort in your Aperture library you might want to use the paid version of PowerPhotos to merge the Aperture library into your current Photos library.

 I ran a number of tests with a 50 photo Photos library with keywords, captions, keywords and locations.  I merged it into an empty library using Photos and PowerPhotos.  This is what I found was imported by each;

PowerPhotos:                                      Photos:

Albums                                               -----------

Captions                                             Captions

Titles                                                   Titles

Original images                                  Original images

Edited images                                     Edited images

---------------                                        Locations

Favorites                                             Favorites

Can detect and exclude                      Duplicates

duplicates or not

Neither method included projects. 

Both methods could import older iPhoto libraries into a Photos library when the iPhoto library couldn't be migrated into a Photos library.
