Application crash after Obfuscation in release build

[Connect-and-Exchange]

After testing in debug mode the application and chromium browser are working fine. Once a release is build and the binary is obfuscated the app crashes the moment the chromium browser is opened in a WinForms Form.

the code is simple:

    UpgradeMessageForm upgradeForm;

      private void ShowReleaseNotes()
      {
          upgradeForm = new UpgradeMessageForm();
          upgradeForm.Show();
          upgradeForm.FormClosing += UpgradeForm_FormClosing;
      }

      private void UpgradeForm_FormClosing(object sender, FormClosingEventArgs e)
      {
          upgradeForm.FormClosing -= UpgradeForm_FormClosing;
          upgradeForm = null;
      }

code of the WinForms:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace MegaCellMonitor
{
    public partial class UpgradeMessageForm : Form
    {
        public UpgradeMessageForm()
        {
            InitializeComponent();
            chromiumWebBrowser1.LoadUrl("https://www.megacellmonitor.com/ReleaseNotes_4_5_1_0");
        }
    }
}

It doesn't matter where i call it from, either through a user control like a button onClick or through a worker which calls the dispatcher and create a new task using invoke.

Does your release build work without obfuscation? If you are testing on a different machine make sure Visual C++ 2019 or greater is installed.

You'll need to contact the support team for the obfuscation tool you are using and ask how to get a meaningful exception. Make sure to mention that CefSharp uses Visual C++ 2019.
