Android PopupWindow not dismisses

Question

I use PopupWindow to show menu in Fragment and then navigate with Navigation Compopnent to another Fragment

override fun createPopupMenu(popupView: View?) {
    if (popupView == null)
        return
    menuPopup = PopupWindow(context).apply {
        elevation = requireContext().convertDpToPixel(10f).toFloat()
        setBackgroundDrawable(null)
        height = ViewGroup.LayoutParams.WRAP_CONTENT
        width = ViewGroup.LayoutParams.WRAP_CONTENT
        contentView = popupView
        isOutsideTouchable = true
    }
}

When I try to close it with menuPopup.dismiss(), it is not always work's because internall check of isShowing() returns false. But PopupWindow visible and closes on touch outside.

Show method is:

override fun showMenu() {
    if (::menuPopup.isInitialized) {
        menuPopup.showAsDropDown(
            some_menu_button,
            requireContext().convertDpToPixel(if (requireContext().isRTL()) -185f else 0f),
            requireContext().convertDpToPixel(8f)
        )
    }
}
