Disable "IPv6" for the network adapter on your computer.
I don't have IP v6 enabled at all on either Windows Adapter or Router, I have checked most of all the previous settings including registry and services etc.
It's something that Microsoft changed on the 1st general release of 24H2 that is causing the problem, my other PC has exactly the same Network card and got a later release of 24H2 and is not affected by it, because I stopped it from downloading for quite a while.
