Error: LXD VM agent isn't currently running

after launch almalinux9 --vm, and it return to this error message “Error: LXD VM agent isn’t currently running” , when I run lxc exec container – bash
if I use lxc start container --conlose, it need password to login (what is root default password)

(tried rockylinux9, and has same issue)

My question is, how to login those vm system ? if “Error: LXD VM agent isn’t currently running”
Thanks
