Reproducer:

adm@tws-corosync3-1:~> sudo -E crm cluster stop --all
adm@tws-corosync3-1:~> sudo rm /var/lib/pacemaker/cib/cib.xml

adm@tws-corosync3-1:~> sudo -E crm cluster stop --all
adm@tws-corosync3-1:~> sudo crm cluster init -ys /dev/disk/by-partlabel/sbd-tws-c3

Can't reproduce for me:

adm@alp-1:~> rpm -q crmsh
crmsh-5.0.0+20241209.20981523-1.1.noarch
adm@alp-1:~> history 
    4  sudo -E crm cluster init --use-ssh-agent -ys /dev/sda5 -N adm@alp-2
    5  sudo -E crm cluster stop --all
    6  sudo crm cluster init -ys /dev/sda6

Not raise UserNotFoundError
