VB.NET Events not Firing - vb.net

Question

I've received a project from another developer. Long story short, the program pulls several thousand entries from an SQL Database hosted on our internal network. The program displays the entries and allows you to filter them for convenience.
Recently we had an issue in which a table in our SQL Database was cleared (It's normally regenerated each day, but for several days it was blank.) Found the issue and solved it (Made no changes to the VB project) to repopulate the table; but since that point the VB project would no longer fire events.
The program is several thousand lines of code long, so I can not post the entire thing; but I will try my best to give symptoms:
The form object can fire events (Form_Closing, Form_Closed, etc.)
The existing controls (Radio button, buttons, picturebox, data grid view, etc) will not fire any events.
If I add a new control (such as a button), it will not fire events.
If a put a debug breakpoint at the sub that should be fired, it will not break.
Here's an example of a method that should be fired but is not fired:
`Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
MsgBox("GOT IT!")
End Sub`
Here's the Form_Load sub:
<DllImport("user32.dll")> _
Private Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
End Function
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
InitializeComponent()
Try
DataGridView_Items.RowsDefaultCellStyle.SelectionBackColor = Color.Yellow
DataGridView_Items.RowsDefaultCellStyle.SelectionForeColor = Color.Black
CheckBox_Highlight.DataBindings.Add("Visible", RadioButton_BD, "Checked")
Try
'Populates the DGV
LoadTable()
TableLayoutPanel_BD_Parts.Visible = True
TableLayoutPanel_PF_Parts.Visible = False
'Exits if no data was pulled from the database
If dbDataSet.Rows.Count = 0 Or pfDataSet.Rows.Count = 0 Then Application.ExitThread()
Catch ex As Exception
Using w As StreamWriter = File.AppendText(logFile)
Log("Function Form1_Load says " & ex.Message & " # " & DateTime.Now.ToString("yyyy-MM-dd") & "_" & DateTime.Now.ToString("HH-mm-ss"), w)
End Using
End Try
BackgroundWorker1.RunWorkerAsync()
formLoaded = True
Catch exx As Exception
MsgBox(exx.ToString())
End Try
End Sub
There is a backgroundworker, but it appears to work correctly and exit out.
All the forms can be interacted with; but do not fire events. (I can change the selection of the radio button, click the button, type into text boxes, etc.)
I know this is a little vague, I'm just hoping someone can give suggestions as to things that could cause this that I can look into. I can provide specifics; but I can't copy the entire code here.
Thanks for any help!

A very strange thing in your code is that you call InitializeComponent() from Form_Load.
Usually this method is called in Form constructor so you can remove it from Form_Load.
I made some test on my PC: if you called twice InitializeComponent() you duplicate every controls in the form and their events doesn't fire anymore maybe because you have two controls with the same name.
