This one has been manually added. You're basically saying lightdm the
greeter is lightdm-kde-greeter. If you don't have it installed, then it
obviously can't start it, so it might be worth double checking that.

lightdm-greeter is the correct setting, lightdm-greeter is managed using
the alternatives system, so if you remove a greeter the system will
switch to another greeter automatically.

Yup, greeter-hide-users was previously set (to true)
in /e/l/lightdm.conf, and is now set
So, can you actually check which one is actually making lightdm crash?
