iCloud Keychain recovery record locked after forgetting previous device passcode

I recovered my Apple Account and I know my current password and trusted phone number. I have only this iPhone 15 Pro and I forgot the previous device passcode. I need to recover my existing iCloud Keychain. Please check my iCloud Keychain escrow recovery status and, if the recovery record is locked, help me with the additional authentication attempts. I do not want to delete my iCloud Keychain data.
