Thanks.

I think the hosts file is too large, which is causing the freeze.

How about this?

    1. # mv /etc/hosts /etc/hosts.bak

    2. # echo "127.0.0.1   localhost localhost.localdomain" > /etc/hosts

    3. echo "::1         localhost localhost.localdomain" >> /etc/hosts

    4. # yast2 lan

       After YasT2 starts up, please disable NetworkManager and
       proceed with the configuration.

    5. Once the configuration is complete, enable NetworkManager and
      exit YaST2.

    6. # mv /etc/hosts.bak /etc/hosts

    7. # systemctl restart NetworkManager

Best Regards.
