Backing up iphone to macos - stuck on contacts sync

A USB sync of my iphone (ios 18.3.2) to a mac (Sequoia 15.3.2) does not advance past "syncing contacts".

It gets stuck at "3/6 syncing contacts".

I've tried a few things - rebooting the iphone into "recovery mode". Didn't work.

Unselecting "sync contacts" and "sync calendars". I thought for sure this would be a workaround, but again it gets stuck on "syncing contacts" !

Anyone know a way to get the backup to work?

It begs the question are you using iCloud to sync those apps?

I back up manually— I see under "Info " the following message:

You can try signing out of your AppleID/account and back in again to sort sync issues:

Sign in to or out of your Apple Account on Mac - Apple Support

What I can say —

The current stable release of Sequoia including bug fixes, security updates is macOS 15.4

Keep your Mac up to date - Apple Support
