iTunes 12.11.0.26, Windows 10, iPhone 12 - Your iPhone has not been backed up to this PC
I have backed up my iPhone 12 (iOS 14.2.2) with an older PC, successfully various times until recently, when I started getting a "Your iPhone has not been backed up to this PC" message even with no error messages and completing the backup.
I just set up a new PC and tried backing up my iPhone 12 with the latest iOS 14.2.2 and the newest iTunes version !2.11.0.26)
When I backup my device, it saves the backup exactly as it is supposed to, in exactly the folder that it is supposed to and I can see the file, but iTunes can't seem to find it there, and after every "successful" backup, I get the same "Your iPhone has never been backed up to this computer" message.
I have read several threads here but I have not been able to find a suitable solution.
Any ideas on how to fix this?
iPhone 12, iOS 14
