Mac & iPhone do not sync all the photos and videos

Hi everyone.

I have a MacBook Air with macOS Monterey 12.6.3 and an iPhone 12 mini iOS 16.3.

I want to sync all my 6871 photos and videos from my MacBook Air to my iPhone 12 mini.

I connect my iPhone withe cable (I tried several cables), I go to Finder, I tap on iPhone, I go to Photo, I select to sync photos from the app Photo (all the photos and videos)

The sync starts and reads my photo library

then starts to copy my 6871 photos and videos

but arrived at 384 phots and videos it stops and copy only 384 photos and videos on my iPhone.

I have space to storage photos and videos on my iPhone 12 mini.

N.B. Just I week ago I had a problem about sync (I cannot sync any photos and videos) and I fix it using this tip:

now the sync works but, I repeat I can only sync 384 photos and videos of 6871 photos and videos
