Today the latest build for chrome browser version got installed automatically which is now 54.0.2840.71 m (64-bit). I am unable to drive the browser using the latest Chrome
I have the exact same problem. The only solution I know of (for now) is to revert back to the previous version of Chrome before the update... if possible. Thankfully I had one machine that had the chrome.exe version I needed as the updated VMs had blown it away.
This helped me: https://productforums.google.com/forum/#!msg/chrome/UFSYuIr1-80/DivHmlqPDAAJ
However I did not have "old_chrome.exe" in the folder. I had the old version directory but the old corresponding exe was gone. If I had not found it on an un-updated PC I would have been screwed.
Edit: I also turned off all Chrome updates so I can control them from now on: https://stackoverflow.com/a/31939624/2246511
