error : Could not save application settings: java.io.IOException: java.lang.AssertionError: Unexpected content storage modificat

I have a message saying "Could not save application settings: java.io.IOException: java.lang.AssertionError: Unexpected content storage modification" when running the android sudio.

Simply renaming/deleting the .AndroidStudio hidden folder in Windows, under your home directory. C:\Users\YOURUSERNAME.AndroidStudio. I renamed mine and I'm back up and running.
Example : 
C:\Users\amardeep.vijay and deleting the .AndroidStudio folder.
