Chrome suddenly crashing just after starting

Having used Chrome for years, it suddenly started failing to open. It gets as far as the opening screen with the Restore? box showing. Whatever I do after a few seconds it shuts down. No error message. I have removed and reinstalled a couple of times without success.

So I ran it in Terminal and get this:

[15881:15925:0521/085530.794880:ERROR:login_database.cc(641)] Password store database is too new, kCurrentVersionNumber=28, GetCompatibleVersionNumber=29

I can't understand what has changed since yesterday. I did install Guayadeque, but can't see how that would affect it.

Can you try this command :

rm -rf ~/.config/google-chrome

Though let me tell you that this will reset all your bookmarks, history. This is kinda like reinstalling chrome. If you had backedup your history into your email id then you can back it up easily after doing this command.

If you don't want to start from scratch try deleting just the lock file:

rm ~/.config/google-chrome/SingletonLock

Worked for me!
