Hi @sha921 thank you for your help! Unfortunately, I'm not able to dismiss an individual window, when this method is invoked, it seems all windows in the group will be closed not only the one calling dismiss(). I'm opening windows in the group using openWindow(id: "window"). And below is my current app.swift code the the window group. WindowGroup(id: "window") { WindowView(some data here) .environmentObject(linkModel) } .windowStyle(.plain)

Hi, you are right it was actually a problem with other parts (legacy) of my code!
