WhatsApp Official App Error: Account Blocked on Android 15

I am writing regarding a problem with my WhatsApp account on my Android phone (Hot 60i, Android 15). Although I am using the official WhatsApp application downloaded from the authorized app store, I keep receiving the message that I need the official WhatsApp to use this account, and my account is not usable. I have already tried updating WhatsApp, restarting the phone and reinstalling the application, but the error persists. My WhatsApp account is registered with the phone number 09019852***, and the account appears to be blocked with the message that this account cannot use WhatsApp. I kindly request that my number be reviewed and my WhatsApp account reactivated as soon as possible, or that I am given a clear explanation of why the account has been blocked and what I should do to restore access.
