Can't migrate

I'm pretty fed up. I've had minecraft for 10+ years and we don't have access to my login email anymore for quite some years now, but in order to migrate you need it for the 2 step authentication which wasn't a requirement back in the day, so in order to migrate I'll first of all have to change my email address, which I can't do because I first have to setup a 2 step authentication to an email which I don't have access to. So on to option B, claiming my account and changing my email through my transaction ID, which is in an email from 10+ years ago in an inbox which I can't access. I get that you need the extra authentication but I've used the same account for so long and never had any issues, and it really feels like I'm in a dissadvantage because I've been a loyal player for such a long time.

I hope someone somehow has a different option or has the same problem because this needs to be fixed.
