Bookworm - Mesa card block internet

Hello,

I installed Debian Bookworm + RIP LCNC 2.9. It has fantastic latency about 20 000 ns with youtube video.

I have problem. If the mesa card is disconnected, the internet works fine for me. As soon as I connect the Mesa card and ping it, the internet stops working.

Network Manager is removed.

/etc/network/interfaces :
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

Not sure, but probably this should be removed
auto enp2s0
You have this
# sitova karta pro MESU1
auto enp2s0
iface enp2s0 inet static
address 10.10.10.1
netmask 255.255.255.0
# gateway neni potreba

But when you connect it, you get this
2: enp2s0: <BROADCAST,MULTICAST,DYNAMIC,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 68:05:ca:5a:65:92 brd ff:ff:ff:ff:ff:ff
inet 169.254.91.41/16 brd 169.254.255.255 scope global enp2s0

So, the IP from the interfaces file is not there, it as as "shared to other PC's".

I don't know what it was. I had to reinstall the entire linux Bookwrom and now it works.
