Google Chrome 68.0.3440.75 is crashing on my older Windows 8.1 x64 system. Had to recover from a system image. On a newer one running since Sunday, 8.1 as well, is working just fine as expected. Never had an issue like this before with Chrome. Chrome launches for approximately 10 seconds then puff! It's gone.
From now on I'm going to install Chrome in shadow mode (Shadow Defender) before doing on the real filesystem. The culprit was a process mitigation I did in the past. lol
I had this as well, disabled all Process Mitigations, and problem solved. Now I have to figure out which mitigation caused it since it is not logging to event log.
@WildByDesign Yes, it was a process mitigation thing, lol. Grabbed GFlagX once again and removed chrome.exe from IFEO registry settings. Solved, phew!!! Chrome is a really nice and stable software. https://www.wilderssecurity.com/threads/gflagsx-with-mitigation-options.394921/page-5#post-2734136
@Mr.X I'm glad it's working well for you now. I will try to troubleshoot the mitigations later and will let you know which one was causing the troubles once I figure it out. I don't understand why a mitigation would react differently from one version to another, but hey, that is the ever changing world of software.
I was able to confirm that the troublesome process mitigation that is causing Chrome 68 to crash is "Validate Handle Usage / Strict Handle Check" mitigation. You can put your process mitigations back to the way they were before, but disable that one mitigation and you should be good to go.
