You're in the live environment, right?

first check if sddm starts:

systemctl status sddm

should be:

Loaded: loaded (/lib/systemd/system/sddm.service; enabled; vendor preset: enabled)
Active: *active (running)* since ...



...this output also gives you more infos about problems...


systemctl restart sddm <-- restarts sddm


otherwise:

Maybe the intel-graphics drivers are not installed or not correctly. Had often such a 
problem with nvidia cards... X freezing...

"apt search xserver intel" shows  you the driver packages

apt install xserver-xorg-video-intel

might be "reinstall" if already present


after that also:

systemctl sddm restart




Hope this helps!
