2FA and Developer account

Hi!

I have a problem. 6 or 7 months ago (I can't remember it clearly) I added an organization and tested it. I could use developer setting so I installed an app with side quest.

but after this time, I signed to my account again to install our first app, but found lost my developer access. I tried to use 2FA (via text service and Google Authenticator app) again, text service not working, also I had my first setting on GA app, however did it again.

now I need this access to test our attempts, to install this app. I requested a friend also to send an invitation and I accepted it to join his organization as a developer but we couldn't fix it.

I'm a nurse that our team is working on an app with medical field (simple games for autism children) so I hope you help me, we spent a lot of time, money and etc..., to get this experience so we hope that can help humanity.
