A highly contagious, highly deadly disease will sweep through humanity. It has happened before, several time. The great flu in 1918 killed about 10% of humanity, the great plague killed about 1/3.
A Carrington Event. That was a super extreme solar flare in 1859. It caused currents in telegraph lines that started fires in some telegraph offices. Such an event today would collapse the entire electric grid and fry lots of home and office electronics. Most cars have electronic ignition and would be dead. All cell phone towers would go out.
Global economic collapse. Modern civilization is increasingly complex and interdependent, like a very complex machine. Eventually something with throw a monkey wrench into the economic gears and the machine stops.
