Why do I have to restore my iPhone to sync it with my PC?
iTunes says I cannot sync and I must restore phone to factory settings

iPhone SE, iOS 17
You can use iTunes to reinstall the software on your device and restore it to its default settings. You might need to do this if you’re having problems with the device (for example, if it freezes or stops responding frequently) of if you’re getting ready to sell it or give it away.
