You could derive a class from the ToolStripMenuItem and override the method ToolStripDropDownItem.OnDropDownOpened(EventArgs) Method (System.Windows.Forms) | Microsoft Learn[^]

Then in your OnDropDownOpened handler, you can scan the Application.OpenForms collection to see if the form exists. If it exists, then you disable the menu item.
The difficult we do right away...
...the impossible takes slightly longer.
