Instagram Account Recovery Request Due to Duo Mobile Authentication Issue

I was using the Cisco Duo Mobile security app on my old iPhone 11 to protect access to my Instagram account through two-factor authentication. My old phone stopped working and will no longer turn on, so I recently purchased a new iPhone 16. However, when I try to log in to my Instagram account on my new phone, Instagram asks me for a verification code from Duo Mobile. Since my old phone is completely unusable, I have no way to access the required code.

Even after reinstalling the Duo Mobile app on my new phone, I cannot generate a verification code. As a result, I am completely locked out of my Instagram account. This situation is causing me considerable difficulty, particularly in terms of account security and maintaining access to my account.

I request assistance in restoring access to my Instagram account, which is currently inaccessible due to the Cisco Duo Mobile authentication requirement. Please clearly explain the necessary steps, including any identity or account verification procedures, and provide a solution that will allow me to log in to my Instagram account again.
