I tried configuring according to your steps, but I'm still encountering the missing file error. I attempted to rename the old icon in Assets to match the new icon's name, which resolved the compilation issue. However, strangely, the behavior differs between my two apps. In the first app: iOS 18 correctly displays the old icon. iOS 26 shows the glass effect normally for both light and dark mode icons, but the transparent icon appears as a tinted icon. In the second app: Both iOS 26 and 18 display the old icon.
