Smash Forge closes when highlighting "Model Editor" option

[CanvasK]

With a character's folder loaded the Model Viewer interface is shown and there is a dropdown with the options Model Viewer, Model Editor, Animation Editor, LVD Editor, ACMD Editor, and Clean. Moving the mouse over the "Model Editor" option causes the program to freeze then close a few seconds later. Clicking on the option is not required, merely having the mouse cursor move over it briefly is all that is needed. Using the arrow keys to select it briefly loads some of the interface but still results in freezing then closing.
