Request to change registered email address (Unable to log in)

Hello,

I am writing to request assistance with my account. I have been playing on this account for a long time, but I am currently unable to log in because I no longer have access to the registered email address. As a result, I cannot check the one-time password (OTP) required for verification.

Is there any way I can change my registered email address to a new one so I can regain access to my account?

Please let me know what information or steps are required to verify my ownership and update the email.

Thank you for your time and help.
