Actually The max-w-screen-2xl class on the NavigationMenu was constraining the width and affecting the natural positioning behavior of the menu components.
and
The NavigationMenuList (the container for menu items) didn't have proper centering - adding justify-center ensures the items are centered within the navigation bar rather than sticking to the left. here is the file with the fixed code .

I have checked with your code . Still not working. I think the issue is in this navigation-menu component of shadcn. Specifically in here they set left-0 but it should be dynamic.

const NavigationMenuViewport = React.forwardRef<
  React.ElementRef<typeof NavigationMenuPrimitive.Viewport>,
  React.ComponentPropsWithoutRef<typeof NavigationMenuPrimitive.Viewport>
>(({ className, ...props }, ref) => (
  <div className={cn("absolute left-0 top-full flex justify-center")}>
    <NavigationMenuPrimitive.Viewport
      className={cn(
        "origin-top-center relative mt-1.5 h-[var(--radix-navigation-menu-viewport-height)] w-full overflow-hidden rounded-md border bg-popover text-popover-foreground shadow data-[state=open]:animate-in data-[state=closed]:animate-out data-[state=closed]:zoom-out-95 data-[state=open]:zoom-in-90 md:w-[var(--radix-navigation-menu-viewport-width)]",
        className
      )}
      ref={ref}
      {...props}
    />
  </div>
));
NavigationMenuViewport.displayName =
  NavigationMenuPrimitive.Viewport.displayName;
