I need help , Enrollment issue

A while ago, I was able to go through the enrollment process all the way to the payment step, but I didn’t have an app ready to publish at that time, so I didn’t complete the payment.

Two days ago, I finished developing my app and wanted to publish it on the App Store, so I tried to enroll in the Apple Developer Program. I attempted the enrollment on both my iPhone and Mac. On the Mac, after taking the required photo, I got an “unknown error”. Then I tried on my iPhone, but when I tapped the “Enroll Now” button, I was immediately shown a message saying “Contact Support”.

After contacting Apple Support, I was told that my enrollment cannot be completed for “one or more reasons”. They couldn’t tell me the specific reason, nor could they tell me when I might be able to enroll again. I’m very confused — I was able to reach the payment step before, and when I searched online for “one or more reasons”, some people said it means being permanently blacklisted. But I have no idea what I did wrong, or why I would be permanently banned without any explanation. This is completely unacceptable.

I am a recent graduate. I need to enroll in the Apple Individual Developer Program to publish my own apps, gain iOS development experience, and try to build a career as an independent developer. However, I am stuck at the subscription enrollment step, and Apple Support couldn't give me any specific reason. I've also read online that this situation might mean being permanently blacklisted. This would be a devastating blow to my career. I truly cannot understand why this is happening, and I'm very confused.
