[SOLVED] Chromium Browser not opening or taking too long to load on Ubuntu 16.04

I have been using Chromium Browser from Google for everyday use. But today, it completely stopped working. I tried to open it via terminal and couldn’t see any error or any log. The process seem to open but not opening the browser at all. I didn’t had any patience and closed it via terminal with command killall -9 chromium-browser . I started using Firefox, but being used to the Chromium Browser and the debug tools I had, I couldn’t resist and started to find the solution. I filtered the chromium-browser not opening in past week in the search result, but doesn’t looks like others are having any such problem. Then I had to do it on my own.
