All of my campaign play records and achievements are gone

So about few days ago, I was playing Warcraft 3: Reforged and I paused the game and closed the laptop and when I got back, not only the game was switched off, but literally all of my campaign play records and achievements were wiped clean, not to mention that whenever I restart those games, they keep begin with cinematics.

What’s even worse is that when it comes to Warcraft 3: Reforged, I cannot play a Singleplayer Custom Games at all. Does anyone know how to fix these issues? And if anyone is curious, no, my region hasn’t changed.
