Arena of Valor Error Code Prevents Access – Can't Enter Game for Over a Month

I’ve been playing Arena of Valor for two years without any issues, but about a month ago, I suddenly started getting an error code every time I tried to enter the game. I deleted and reinstalled the app, but this didn’t resolve the issue, and I still can’t access the game. This has happened once before, but back then, simply exiting and re-entering fixed it. This time, nothing works, and I’m completely locked out. I don’t understand the cause of this problem and am frustrated with being unable to play for over a month now. I need immediate assistance to resolve this error code so I can get back to enjoying the game.
