This question already has an answer here:

When I try to launch google-chrome, I get the following message:

Failed to create a ProcessSingleton for your profile directory. 
This means that running multiple instances would start multiple browser processes
rather than opening a new window in the existing process. 
Aborting now to avoid profile corruption.

I tried to uninstall and reinstall Chrome following the advice here How to install Chrome browser properly via command line?, which did not solve my problem.

How should I proceed?

Your .config and .pki folder in home directory might be assigned with root permission.

Type sudo chown -R {username}:{username} ~/.config ~/.pki

Note: Replace {username} with your username that you are logged on in.
