Access denied after samba installation

i installed samba and mosquito on my pi zero w

and after the installation of samba my system rebooted and ever since I couldn’t login , when trying through ssh my login says access denied, and when watching via HDMI , i see the system is busy and never reach login,
i haven’t changed the password and I’m surely inserting the right password, i don’t have access to samba since i didn’t get to make a user before the system rebooted,
