I have one user, if I click switch user the session is closed then SDDM appears, I type my password then press enter but the splash screen freezes indefinitely and I should manually force power off my laptop to use it again.
The solution is to set ReuseSession to true in /etc/sddm.conf , I don’t know why Manjaro has false as default value which causes problems and prevents reusing current session.

It’s not the same problem, mine is caused by faulty settings in SDDM that causes it to start new session on another tty with same user that has already opened session on another tty.
