Chrome suddenly crashing just after starting
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!
