Try to login as a new user (or move your home directory out of the
way). If it works start selectively deleting dot files/directories
from your home directory. Start with .cache, .kde4 and everything that
starts with a k in .config and .local and go from there. I had the
exact same problem when I upgraded one of my laptops and that's how I
fixed it. Also delete anything in /var/cache and any files belonging
to your uses in /tmp and /run.

You can also try switching to a VT and kill plasmashell and if it
doesn't restart automatically start it with the DISPLAY environment
variable properly set.

Also look at the system logs, .xsession-errors, xorg logs, etc for
clues. You can also run kdebugdialog5 from another DE to enable a lot
of kde debug output to the system logs.
