I wonder why DHCP broke, stopped working, fails after 1909

I did a windows update/upgrade from Windows 7 to Windows 10 and it installed 1909. Once I completed the install/upgrade most things worked except the network driver would not obtain an IP address via DHCP. Once I manually set it up the network works but I would love for it to get its address dynamically so I don't have to set up another reservation. :) Any thoughts regarding this?
