Como Desactivar Las Aplicaciones En Segundo Plano Windows 11

I have been facing the issue since Monday, Sep 18th, when I updated my iPhone 11 Pro Max from iOS 16.x to iOS 17. In Settings, the message "iCloud Data isn't Syncing" is displayed. When I click the Resume Data Sync option, I am prompted to enter my iPhone Passcode. After entering the Passcode am prompted to Enter the Recovery Key. I don't have the 28-character Recovery Key, so I have been entering the Recovery code generated on my Recovery contact device. Once the Recovery Code is entered, I see the screen (attached) in the settings menu.
