AWS-MFA, Authentication Issues, Account Access, Billing, Security Key, Windows Hello

I am unable to access my AWS account because I had configured Multi-Factor Authentication (MFA) on a Windows device using Windows Hello (fingerprint). Unfortunately, I have lost that computer and can no longer authenticate using my original MFA method.

I attempted to use the "Resolve MFA issues" option, which should send a verification call to my registered phone number (ending in 2901). However, I am not receiving any calls from AWS, even after multiple attempts.

I urgently need access to my account to download my invoices, but every recovery method I have tried has failed. Since I cannot log in, I am unable to contact AWS support directly.

Could anyone advise on alternative ways to bypass or reset MFA in this situation? Is there a way to manually request support without logging in?

Thanks in advance for your help!
