To help narrow this down:
- Are you trying to transfer pictures from your Windows 11 PC to your iPhone's Photos app?
- Are you currently using iCloud Photos?
In the meantime, you can use Apple's Apple Devices app to sync pictures:
- Install "Apple Devices" from the Microsoft Store.
- Connect your iPhone to your PC using a USB cable.
- Unlock your iPhone and tap "Trust" if prompted.
- Open Apple Devices and select your iPhone.
- Select "Photos" and enable "Sync Photos to your device from".
- Choose the folders you want to transfer and click "Apply".
For detailed instructions, see Apple's guide:

Note: If iCloud Photos is already enabled, use iCloud to sync your pictures instead.
