Getting error in Access database connection - vb.net

Question

I'm trying to connect to my database and I'm getting this error message (ex):
I've another function which opens DB and load some data, it works fine without any error... But when I try to use this, it returns me this error, the line 175 is "cn.Open()".
My connection string and Local_DB is both same as other functions which are working without errors.
Private Sub AtualizaClientes(ID As Integer)
' Local da DataBase
Dim Local_DB As String
Local_DB = "C:\Users\Heitor BASAM\Desktop\Sistema\DataBase_Sistema.accdb"
Try
Dim cn As New OleDb.OleDbConnection
cn.ConnectionString = $"Provider=Microsoft.ACE.OLEDB.12.0;Data Source={Local_DB}"
cn.Open()
cn.Close()
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub

Glad you fixes your problem! Just a few bits to tidy up the code.
Always use Using...End Using with database objects that expose a Dispose method. They may be using unmanaged objects and their dispose methods must run to release these resources. The End Using takes care of this for you even if there is an error.
You can let the error bubble up to the calling code, user interface code. Wrap the call to AtualizaClientes in a Try...Catch...End Try
Private Sub AtualizaClientes(ID As Integer)
Dim Local_DB = "C:\Users\Heitor BASAM\Desktop\Sistema\DataBase_Sistema.accdb"
Using cn As New OleDb.OleDbConnection($"Provider=Microsoft.ACE.OLEDB.12.0;Data Source={Local_DB}")
cn.Open()
End Using
End Sub
EDIT
You would add the Try...End Try to the UI code. Example...
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim id As Integer = 7
Try
AtualizaClientes(id)
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub

I figured out the problem! I've a function when a especify textbox is changed, it calls this "AtualizaClientes" function. The problem is, when you load the form, it runs a "TextChanged" event in every textbox and trys to run the database before loading it. This was causing the error message.
To solve this problem, I made a boolean variable which returns true after loading the database. So, I changed my textchanged event to run only if this variable is true.
