Did a world update recently and have run into a new issue I cannot resolve. My system's NIC is no longer getting assigned its IP address on boot.

I use Network Manager and a systemd configuration. I have (had) it setup to assign a static IPv4 address, gateway, and DNS IP. See below from nmcli con show
"Profile 1"

Here's the output of ip a s (note that I have no IPV4 address)
Code:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host noprefixroute
       valid_lft forever preferred_lft forever
2: end0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether ca:13:73:9f:2e:07 brd ff:ff:ff:ff:ff:ff
    inet6 fdcc:e0f4:6b01:7949:360c:1bc:bf32:daa5/64 scope global dynamic noprefixroute
       valid_lft 1781sec preferred_lft 1781sec
    inet6 fe80::c7b5:9b6a:46cb:2c3/64 scope link noprefixroute
       valid_lft forever preferred_lft forever





The config is correct as far as I can tell, but the end0 device is not getting assigned its IP address by Network Manager. No change if I restart Network Manager either. The only way I can get an IP right now is to manually assign it with either an ip or ifconfig command, which gets me online but doesnt help me when I reboot and get right back into a no IP state.

I'm stumped. Everything looks fine. No errors anywhere that I can tell...

Plz delete it and recreate it.
Code:

nmcli con del "Profile 1"
nmcli con add type ethernet con-name end0 ifname end0 ip4 192.168.86.20/24 gw4 192.168.86.1
nmcli con mod end0 ipv4.dns 192.168.86.5 ipv4.method manual
nmcli con up end0
systemctl enable <NetworkManager>

Maybe systemd changed the iface name from eth0 to end0.
