Unable to Change Password and Access Genshin Impact Account Due to Security Issue

I recently purchased a Genshin Impact account and, as expected, updated the credentials to make it my own. While attempting to change the game password, I encountered a recurring error message: "Refresh the page and try again." Despite multiple attempts, the password remained unchanged.

Later, when I tried logging in again, I received a notification stating, "Account security at risk, please wait," and I’ve been locked out for three days now. I’ve uninstalled and reinstalled the game, but the issue persists. This is extremely frustrating, and I urgently need assistance to regain access to my account. Please help resolve this issue and restore my account's functionality.
