Error: Failed to init interfaces

Additional Note:

When we run instance1.json & instance2.json without tx-threads & rx-threads, we were able to run both instances parallelly

Please provide:

sudo ethtool -i eno2
sudo ethtool -i eno3

Does it work if you start instance 2 (sudo bngblaster -C instance2.json -S run.sock -I) without instance 1 running?
