Handling exception In CreateDynamicButtons

**Form1.cs** - Consider handling when executable paths become invalid:
```csharp
// In CreateDynamicButtons, you might want to show a warning icon for invalid paths
if (!File.Exists(item.ExecutablePath))
{
    // Show warning overlay on button
    button.BackColor = Color.FromArgb(60, 30, 30); // Reddish tint
}
```
