I update my system today and a few minutes after the update was done, my system started to fall apart.
Everything began with icons of the window controls not showing up anymore. Further I could start any applications anymore as if they weren't installed. Wingpanel and plank were closed and not startable from the terminal, too.
I tried to restart my computer, but it's stuck on the elementary logo. On recovery mode I can boot however.
Never had an issue like this before, so no idea what to do about it. Any suggestions?
