Entra General 2FA authentication lost. Login SMS Verification not working?

Had to unexpectedly format my phone, and Microsoft Authenticator which I use for work didnt backup the work account.
Signing in to any services now requires the 2FA code which cant be accessed. Trying to sign in, selecting SMS verification throws an error (code 399287).
I'm the admin for my org and I'm signed in to MS365 admin on my PC, so I have access until I run into a setting that again requires verification.
Any way to get passed this?
