System.ArgumentException when trying to edit the top link bar

Question

Whenever I try to edit the top link bar of my SharePoint site, I get a page that just says "New Navigation Link."  That's fine, the link bar is empty, but when I click on that, IIS crashes:
Server Error in '/' Application.
Value does not fall within the expected range.

Hi,
According to your description, my understanding is that the error occurred when editing the top link bar in SharePoint 2013.
As the error message is very common, I recommend to check the ULS log for detailed error message for further research.
For SharePoint 2013, by default, ULS log is at C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\LOGS.
Here is a similar thread for you to take a look:

Best regards.
