Issue Type: Bug

I dont know how it happened.
I began using VS one day and noticed that the Menu Bar dissappeared.
I attemoped to press and then hold the key but it does not reappear.
I navigated to visual:toggleMenuBar it is unresponsive to change
attempted Keybinding change. Still no effect
Json value continues to reset to default when is pressed
