Sequoia: Issue with Audiobook Syncing Between Mac and iPhone After macOS Update

Shortly after updating to macOS Sequoia, I lost the ability to import audiobooks that I uploaded from the Books app on my Mac to the Books app on my iPhone. The problem is that the list of books stopped updating in Finder when opening the iPhone, specifically in the Audiobooks section. It displays some old list of books that were long deleted from both the Mac and iPhone. At the same time, I can't transfer new books to the iPhone because they simply don't appear in the list.

I tried to find the plist containing the audiobook library on the Mac, but I couldn't find it.

There is a file at /Users/$USER/Library/Containers/com.apple.BKAgentService/Data/Documents/iBooks/Books/Books.plist, but it only contains regular books.

The actual audiobooks downloaded to the Mac library are located in /Users/$USER/Library/Containers/com.apple.BKAgentService/Data/Documents/iBooks/Books/Audiobooks, but there is no file indexing the books there.

How can I remove the outdated audiobook list from Finder and get it to sync audiobooks between my Mac and iPhone again?

Currently, I have to do this on a Windows computer where everything works through iTunes.
