Why is my MagSafe charger not working after iOS 18.1 update?

I have an iPhone 15 pro max, with ISO 18, the magsafe battery pack and the magsafe charger charged my iPhone normally, but since I updated to ISO 18.1 my iPhone stopped charging with these 2 magsafe chargers, it only recognizes the charger but not It charges for nothing, I restart the device and get it to charge, but this always works, does anyone have the same problem? Or could it be that Apple not only eliminated these two chargers from its catalog, but also made them obsolete.
