How to Crack Instagram 6 Digit Confirmation Code When You Have the Password?

Instagram wants me to confirm my email address but I do not have access to it anymore, I've been contacting Instagram for months but no hope. my only hope is to somehow break the 6 digit code that it sends to my old email, is there any way for that? I tried over 100 code at the same time manually and it didn't stop me so it might do the same thing for a cracker? thanks
