WePlay Blocked My Account and Device Without Warning

I have been using the WePlay game voice room app and today, at around 5 pm, my account and even my device were suddenly blocked without any explanation. I was not online at the time, and I did not receive any prior warning, notification or reason for this action. I do not understand why my account and device have been blocked and this situation is causing me serious inconvenience, as I can no longer access the app at all. I kindly request that my account and my device be urgently unblocked and that this unnecessary restriction be removed.
