Unable to Delete VPC

I'm trying to delete my VPC and it tells me that it could not delete the VPC vpc-0d0352db85946344f
because 'eni-02512da6987229078' is currently in use.

I'm not able to see what is using that ENI, and I've already deleted the rest of the things I have access to in the VPC.

Can you help me to identify what is wrong with this ENI?

Thanks!
