How to Change Email Address on My Genshin Impact Account

I’m unable to change the email linked to my Genshin Impact account. Initially, I registered with a random email I rarely used, then stopped playing for a long time. When I returned, I realized the account was still tied to that email, which I’ve since deleted.

Now, I can log into the game, but I can’t link it to a new email address because the system requires a verification code sent to the deleted email. This situation is frustrating, and I need urgent assistance to resolve it. Please provide a solution to allow me to link my account to a new email and secure my Genshin Impact progress.
