I wanted to update my previous post.
Apple Developer Support told me that they reset my Apple Developer Program enrollment. However, the issue still remains.It seems that the incorrect name is still stuck specifically inside the Developer enrollment flow, even after the reset.
My Apple Account now shows my correct legal name, but when I try to enroll in the Apple Developer Program, the old incorrect name still appears and I cannot edit it.
At this point, I have contacted Apple Developer Support again and asked for their official guidance regarding a more complete reset, including whether permanently deleting my current Apple Account and creating a new one would be a possible solution.
If Apple confirms that one of these options is possible and actually resolves the issue, I will update this post for anyone who may face the same problem in the future.
