Steps to reproduce? Were you trying to attach another screen?
I've just updated, rebooted and tried to login. After a while the splash screen vanished and nothing else happened. I switched to virtual console, logged in and checked processes. There's no plasmashell, no krunner. So I tried 'export DISPLAY=:0; plasmashell'
This is fixed in plasma-workspace-5.2.0-7.fc23.x86_64 and qt5-qtbase-5.4.0-13.fc23.x86_64
