Keychain disappears after iPhone reboot in iOS 18

When I reboot my iPhone 14 pro with Live Activity started, KeyChain 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.

Is this an app that you’re developing?

@DTS Engineer Yes, this is a problem that occurs in the app I am developing.

Hi ,I wanted to know, when you get logged out and close the app, then reopen it, are you still unable to find the Keychain data?

In fact, my app is also facing a similar issue, and I’m wondering if it could be related to a pre-warming problem that saw in iOS 15.
