KDE SDDM Autologin Inconsistent

I have an /etc/sddm.conf Autologin entry. The account name entry is the only account which I created when I install KUbuntu LTS 26.04 on an AMD platform. Sometimes the autologin works. Sometimes it doesnt. Is this a known issue and/or is there a fix and/or should I be doing autlogin through some other method?
