Tracks Not Loading into Decks

I recently migrated my library to a new computer (macbook pro 2022 running osx ventura) and moved my database and all my music files to an external hard drive. Was able to use my library backup and auto relocate all my files but a lot of the tracks won't load into the decks to play, and i'm not getting any kind of error message indicating what's wrong, they just won't load. Wondering what might be the solution to this.
