The short question is: if I have an app (Chrome) that keeps on crashing on app start up, how do I reinstall the app totally so it will run again? (removing the app and download and reinstall won't work).

The long question is:

I have an iMac on the top floor of the house, in California, and some days the thermometer showed a max temperature of 39C (which is 102F). That day, when I see the Google Chrome window, I clicked on it, and it crashed.

At that time, the temperature of the room is probably around 36C.

So to prevent any further damage to the computer, I shut it down and wait until the next day in the morning to power the computer up again.

But now Google Chrome will start up and immediately crash. I tried going to the Applications folder, delete the whole app, and use Firefox to download Google Chrome from the Internet again to install it. But the same thing happened. Install, reboot, app crashed. Reboot again, run the app again, and it crashed again. I reinstalled the app for about 3 times total.

And since it might be related to the app setting data having some issue that caused the app to keep on crashing, I found the folder where the app data sits: `~/Library/Application Support/Google`, and I renamed it to `~/Library/Application Support/00G00gle` and tried and removed the app and downloaded the app and reinstalled it. But still it crashed.

So is there a way to totally reinstall the app in this case to make it work again?
