Severity: Dear Maintainer, I am experiencing an authentication error when
waking my laptop from suspend or after closing the laptop lid on Debian 13
(Trixie). Steps to reproduce: 1. Close the laptop lid to trigger system
suspend. 2. Open the lid to wake the laptop. 3. The lock screen appears,
but typing the correct password results in an "Authentication error"
beneath the password field. Expected behavior: Typing the correct password
should successfully log me back into my session. Actual behavior: I am
permanently locked out with an "Authentication error" message and have to
force a reboot or manually unlock via a TTY console using loginctl.
