Why can't my phone connect to my Win 11 PC?

Is your phone an Apple iPhone or is it some sort of Android device?  If you are looking to use the new Windows feature called PhoneLink it isn't compatible with Apple mobile devices, only Android devices.

If the bluetooth connection does not work, try to connect phone to Windows 11 via the USB cable.

First, turn off Bluetooth on both devices. After that, restart the devices. Finally, turn of Bluetooth again.
