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.
Tried this and much more, including deleting and reinstalling Chrome. Today, I tried disabling hardware acceleration, with no luck. Then I started to disable extensions. BINGO!! It was Malwarebyte's BrowserGuard. I will alert Malwarebyte of this bug.
UPDATE. I did alert the Malwarebytes team, and they opened a support ticket, but found no issues, so since all was working well, without their Browserguard extension, I asked them to close the ticket. Then I found that Chrome had been updated on 7/14, so I REactivated Browserguard, now find, the issue has been solved, Chrome now runs without suddenly closing.
