My fault was that I tried to find NetworkManager manager messages in dmesg log. I have never tried to enable control of ifupdown interfaces in NetworkManager. In my opinion, on laptops commenting out interface in /etc/network/interfaces and so delegating it to NetworkManager has a clear advantage. Plugged in cable is detected immediately. With dhclient running by ifupdown, it may take some minutes till next DHCP request is sent.
The system may have significant changes in respect to defaults. Concerning NetworkManager, the following commands might give some additional info
networkctl nmcli device nmcli connection /usr/sbin/NetworkManager --print-configI am unsure if the line in /etc/network/interfaces had some effect since device name is enp19s0 and the file contained eth0.

[ 2.771916] r8168: module verification failed: signature and/or required key missing - tainting kernel
tells that not r8169 from default kernel is used. What is the reason to install r8168 and what is its origin? r8168-dkms? From realtek site directly?
I asked concerning more detailed lspci output and firmware package, but I have got no response. If firmware is installed then I would try backports kernel.
If cabling issues have been ruled out then perhaps it is time to ask in a realtek-related mailing list/forum/bugtracker.
https://wiki.archlinux.org/title/Talk:Network_configuration/EthernetSo after configured the interfaces, you could try to add "iommu=soft amd_iommu" to the kernel command-line
Even if it might help, do not forget to disable it if it has no effect. To verify
cat /proc/cmdline
