WhatsApp Stuck on Loading – Unable to Send or Receive Messages

I am facing a serious problem with my WhatsApp account registered with the number +91 6396137*** on my Vivo phone in India (Uttar Pradesh, PIN 243***). For quite some time now, WhatsApp is continuously showing (loading) on the screen and my account is practically unusable. No messages are being sent from my side and no messages are being delivered to others. Because of this continuous loading state, it feels like my account is blocked or stuck and I am unable to communicate with anyone via WhatsApp. I kindly request that my WhatsApp account be checked and reactivated so that the loading problem is resolved and I can start using my account normally again.
