Keychain disappears after iPhone reboot in iOS 18

When I reboot my iPhone 14 pro with Live Activity started, Keychase information disappears. So there is a problem that I have to sign-in again when I enter the app. There is no problem rebooting the iPhone without Live Activity. iOS17 didn't have this problem.
