Ok, thanks.
Here's the relevant part of the log:

2月 26 21:34:29 athena systemd-udevd[499]: eth0: Failed to rename
network interface 2 from 'eth0' to 'enp0s31f6': Device or resource busy
2月 26 21:34:29 athena systemd-udevd[499]: eth0: Failed to process
device, ignoring: Device or resource busy

So, systemd-udevd does attempt to rename the interface but something is
trying to use the network interface before it has been renamed, which is
why the rename fails.

Now you need to find out what part of the system is using eth0 early in
the boot process.
