I also faced this same bug. I was casting video from my laptop to chrome cast- for about one hour it worked fine and then suddenly video stopped and laptop did not respond at all. It did not take any input. So, I had to hit the power button and switch it off and start it again.
-Was using Chrome browser to cast the tab to watch the video online.
-My computer is Dell Inspiron 7000 with Intel core i7 8th gen cpu
