Given that the file name is /home/eddie/.config/google-chrome/SingletonLock, open a terminal.
ls <------------"list files" to confirm the file is present.
mv SingletonLock SingletonLock.bak <-----------renames to file.
rm SingletonLock <--------deletes (removes) the file.
Alternatively, open your file manager, tell it to show hidden files (how to do that varies with the file manager--see the help files).
Navigate to /home/eddie/.config/google-chrome/, highlight the file, and right-click and select delete or rename.
