In case you have tried to delete a Safety Group, or VPC, or varied different sources and also you get the dreaded Community interface is in use by one other service error, then you’ll be able to resolve this by deleting the useful resource by the API.
The right way to delete the Community Interface (ENI)
aws ec2 delete-network-interface --network-interface-id eni-xxxxx
Substitute the eni-xxxxx with the ENI id that you’re struggling to delete.
The right way to discover what companies are utilizing the ENI

vpc="vpc-xxxxxxxxxxxxx"
aws ec2 describe-internet-gateways --filters 'Identify=attachment.vpc-id,Values='$vpc | grep InternetGatewayId
aws ec2 describe-subnets --filters 'Identify=vpc-id,Values='$vpc | grep SubnetId
