Here are the files of the networkmanager systemd-networkd conflict (I already removed ifupdown, the problem is the same, so we say for sure networkmanager or systemd-networkd causes the problem)

the output of ip a is the following:

the profile that should come up has addr-gen-mode=stable-privacy, so somehow it adds another ipv6 address, but it totally ignores ipv4...
