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 occured
The username or password you entered is not correct.
Any hints to find more details what's the cause or a solutions to this?
