I upgraded from 10.14 and after that my login keychain is not usable anymore. All operations adding keys or certificates fail. It doesn't matter whether I use Keychain Access.app or other applications like Xcode want to add anything.Importing a .p12 fails with:An error has occurred. Unable to import an item.You failed to provide the necessary administrator authorisation.Exporting seems to be broken by the UI. I cannot enter either a password for the p12-container nor my system password as the secure textfields refuse any input.Creating a CSR results in the following error:An error occuredThe username or password you entered is not correct.Any hints to find more details what's the cause or a solutions to this?

When callingHKHealthStore.requestAuthorization(toShare:read:completion:)in an app that uses a SceneDelegate this results in[Assert] Error in UIKit client: -[UIWindow setScreen:] should not be called if the client adopts UIScene lifecycle. Call -[UIWindow setWindowScene:] instead.which makes using HealthKit impossible at all. NSHealthShareUsageDescription is set. It happens from beta 1 up to the current beta 4.Does anybody have a solution for this?
