Iphone 14 not Syncing with Windows 10 - Itunes wants to upgrade iphone to IOS 17.4.1 but it is already on it

I only have 22 songs on my Iphone out of 313 songs in ITunes Library). When I try to sync I get a message asking me if I want to install IOS 17.4.1 but it is already on that! Not sure if this is the issue. If I cancel & sync, the top display shows steps 1-4 quickly. but no songs are transfered to IPhgone

My wife's iphone is fine (uses a separate ID on the same Windows 10 PC)

Any help much appreciated
