Etsy Country Selection Error Hinders Sign-Up

I'm excited to become a part of the Etsy community, but I've encountered an unforeseen challenge while going through the registration process. Upon reaching the country selection step, an annoying blue error message appears, hindering me from finishing the sign-up process.

I've thoroughly reviewed my information, making sure that every detail is inputted correctly. Unfortunately, the error message continues to persist, which is preventing me from moving forward. I'm completely perplexed by this problem and in dire need of a resolution.

I would greatly appreciate prompt assistance in resolving this issue.
