I am getting a stack overflow after I click the X on the form to close. It happens right after the form closed event. I am using Visual Studio 2017 and VB .NET. Any ideas how to trace this down? Call stack seems small to cause an overflow. Also, why is it going to assembly, even the things in the call stack go to assembly for me when I double click. Error:
System.StackOverflowException
HResult=0x800703E9
Source=<Cannot evaluate the exception source>
StackTrace:
<Cannot evaluate the exception stack trace>
My code:
Private Sub frmViewAll_FormClosed(ByVal eventSender As System.Object, ByVal eventArgs As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed
Try
formClosing_Renamed = True
'JC.Global.StudyForm.Activate()
Catch ex As Exception
End Try
End Sub

I was able to simplify code to this and still get the error so it must be a designer issue:
Friend Class frmTestForm
Inherits DevExpress.XtraEditors.XtraForm
Public Sub setMode(test As Boolean)
End Sub
End Class
Designer With Everything commented out has the issue still:
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> Partial Class frmTestForm
#Region "Windows Form Designer generated code "
' <System.Diagnostics.DebuggerNonUserCode()>
Public Sub New()
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeComponent()
End Sub
'Form overrides dispose to clean up the component list.
'<System.Diagnostics.DebuggerNonUserCode()>
Protected Overloads Overrides Sub Dispose(ByVal Disposing As Boolean)
If Disposing Then
If Not components Is Nothing Then
components.Dispose()
End If
End If
MyBase.Dispose()
End Sub
'Required by the Windows Form Designer

'Me.PerformLayout()
End Sub
'Friend WithEvents txtSearch As System.Windows.Forms.TextBox
#End Region
End Class
Error is happening on the MyBase.Dispose()
