Hi..I am getting an error "The system detected an invalid pointer address in attempting to use a pointer argument in a call"

I  have a Visual Studio project that automatically connects to my mysql database when run. My project suppose to connect to database and display the data on my data grid when opened or executed. The connection was working before, but since yesterday I started getting issue. 

MySql workbench version is 6.2.2
MySQL connector_net 6.9.3
Windows Visual Studio 2013
OS is Windows 8 x64 bit

any advice or solution is appreciated.. Thanks

How to repeat:
-open Visual Studio 2013
-create new project
-create windows form
-click "add references" -select "system.data" and "MySQL.data" click add
-type "Imports MySql.Data.MySqlClient"
- then

            Dim conn As String = "Database=ngp;data source=localhost; user id= root; password=*******"
            Dim connection As New MySqlConnection(conn)

            MsgBox("Database connection has been established.", MsgBoxStyle.Information)
        Catch ex As Exception

        End Try

-save and run for debugging

I do not understand how Workbench is involved here at all?

I have a similar issue like this.--#70676 [Com]: Unable to connect to local MySQL database from Visual Studio 2012..however, I am using a newer version of MySQL and VS. So I don't know what steps do apply.
