Issue With Parental Verification – Invalid Parameters Error (BGMI)

I have been experiencing a persistent login problem in BGMI since 7 September. When I try to enter the game and go to the lobby, a window titled “Gameplay Management System” appears asking me to enter the mobile number of my parent or guardian. After entering the number, an “Invalid parameters” error shows on the screen and I am not able to proceed to the lobby or play the game at all. Because of this error, I am completely blocked from accessing my account and normal gameplay. I have not yet been able to resolve it myself and have not received any guidance within the app about how to fix this specific “Invalid parameters” issue. I kindly request that my login be fixed and this “Invalid parameters” error be removed as soon as possible so that I can enter the lobby and use my account normally again.
