W10 ver 1909. Working flawlessly with Chrome for 3 years. For 2 days now, it has been randomly closing, without warning. All other computer functions remain normal. A few hours ago, it wouldn't stay opened for more than 3 minutes. Not a gamer, just browsing and email. Right now, it's staying open. Virus and Malwarebytes real time scans are clean. Not overheating.

Any thoughts.
