I have not experienced any crash in Chrome, but other apps. Clearing cache and stored data always worked for me.
Here is how to do: Go to settings, apps & notifications, app info then Chrome. Below you'll find Storage, tap it. You will see two buttons: Manage Space and Clear Cache. First clear the cache to see if it solves your problem. If not go into manage space section by tapping the button. Be careful, this will erase all stored cookies, etc. If you are sure there is nothing to loose, clear everthing. Hope this helpes.
