nm-dispatcher connectivity-change

[Hiisi]

Dear users!
Since recently I'm unable to boot my system (f28) with the following
problem. It start to boot normally and just before the login screen would
normally appear it drops into terminal with some messages regarding
nm-dispatcher connectivity-change. It says something that it runs some
scripts but it stucks there forever. I've been messing with python earlier
today. Could it possibly be the cause? I'm able to boot the laptop from
live-usb (this is how I write to the list now), so it shouldn't be a
hardware issue. I was trying to google it but seems people having this
problem with their systems running (unlike mine). Is there a way to fix my
OS without the pain of reinstalling?
TIA
