Button Found, but Throws Exception Clicking or Invoking?

[fuzzevans]

I am trying to automate an application installer using c# and FlaUI v2 (I'm interacting with an installshield wizard). I am able to successfully bring my desired application to the foreground, and seemingly set focus. I then gather all buttons, and prompt if I find a button named 'Next >' (the name I gathered from FlaUInspect v1.3.0)

The prompt occurs indicating a button with the correct name is being found - but the button.click event throws an exception.
FlaUI.Core.Exceptions.NoClickablePointException: Exception of type 'FlaUI.Core.Exceptions.NoClickablePointException' was thrown.

I saw several threads suggesting that you should use Invoke() instead, so I've tried that, but get this exception:
System.InvalidOperationException: Operation is not valid due to the current state of the object.

Can anyone advise on how to actually click the button now that FlaUI has found it?

Code:

using (var automation = new UIA2Automation())
{
var mainWindow = application.GetMainWindow(automation);

if (mainWindow != null)
{
    mainWindow.SetForeground();
    mainWindow.Focus();
    var buttons = mainWindow.FindAllDescendants(x => x.ByControlType(FlaUI.Core.Definitions.ControlType.Button));
    foreach (var b in buttons)
    {
     if (b.Name == "Next >")
        {
            MessageBox.Show("found: " + b.Name);
            //I'm using click OR invoke, not both. Including both as reference
            b.Click();
            
            var invokePattern = b.Patterns.Invoke.Pattern;                           
            invokePattern.Invoke();
        }           
    }
}

}

Messagebox indicating the button is being found:

Apologies, I can't seem to get the formatting to work for my code block...

In a similar case (with check boxes) I use a helper as a workaround:

        public static void ClickCenter(this AutomationElement elem)
        {
            Mouse.Click(elem.BoundingRectangle.Center());
        }

        static void DoCheck(CheckBox cb, bool on = true)
        {
            if (cb.IsEnabled && (bool)cb.IsChecked != on)
            {
                try
                {
                    cb.IsChecked = on;
                }
                catch (InvalidOperationException ex)
                {
                    cb.ClickCenter();
                }
            }
        }
