Cannot login with ssdm

I can not login into manjaro. my password is ok and I test it with tty.
The problem started when I was killed the systemsettingm5 (i think) and some of the icons disappear, i restarted the machine and ssdm was changed.
I cant use my password because there is no button to log me in even “Enter” not working.
(Im sorry for my bad English)

Try in console mode (Ctrl+Alt+F2) to check if the user is blocked.
Removing ~/.cache dir and executing sudo systemctl restart sddm.service maybe fixed isue. if not check journalctl for errors.
