They can coexist. NetworkManager in default configuration ignores

Detailed messages from NetworkManager related to carrier change
events are missed in the posted log file, so the interface is
configured by ifupdown.
Sorry Max I always knew that they cannot, my mistake…
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-config
I am unsure if the line in /etc/network/interfaces had some effect since
device name is enp19s0 and the file contained eth0.

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.

So 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
