I wanted to know why pfsense is blocking Autoconfiguration IPv4 Address.

I am setting up a domain controller. When adding the static IP Address to the Window server, it is not able to get network access. Can that be the reason why I am not able to get network access because Pfsense is blocking the Autoconfiguration IPv4 Address ?

They are blocked because they have no business hitting the firewall. They can still communicate locally, but it's link-local/L2 traffic that can never route outside of its segment.

You'd only receive one of those IP addresses if you had no DHCP service running. You can't use those addresses as your local network the same way you would use an RFC1918 network.
