I am experiencing the same issue. Do you have an Apple device associated with your Apple account? I’ve been locked out for 6 weeks. The “too many codes” issue does not seem to clear itself no matter how long I wait in between login attempts.

Same here and I’ve been experiencing the issue for about 6 weeks. I’ve tried account recovery but the issue remains even after changing phone number. I have waited 48 hours between attempts and the issue remains. The Apple account is not associated with a device because it’s a work account and I don’t want it linked to my personal devices. The annoying thing is contacting Apple Developer support requires me to be logged in, which I cannot do.
