Hi Sonali, It may be still routing that shared guest network. Try to restart your virutal router and virtual machine or shutdown your VM before removing that NIC. let me know the logs when you remove that NIC.
Thank You.

Then I added "isolated guest network" nic to it. Made "isolated guest network" NIC as default and tried to remove "Shared guest network" NIC, but its failing with null exception. I have attached logs. Thanks, /sonali
