[CLIENT] Stuck in a "Ghost Game" + No XP/LP Gain or Series update.

After winning my latest Solo/Duo Ranked Game, despite 2 very toxic people in my team that I'll would have reported, I had to Skip Waiting for Stats as it was unusually long.

Back on the client, I notice that the win was not counted in the league, but in my Match History it appeared as a Victory, but with no Rating (A+, B-, C...).

So I restarted my client and when I logged back in, I'm launched into a game, but it just keep me on a black screen that doesn't go out when I Alt+Tab, and if I close the window, I can only try to reconnect to the game, and end up on the same black screen.

It is displaying me in a new game, playing as Garen (the champ I had), for some seconds (the time I spent since I relogged into the game), but with no gamemode displaying.

My friend who was in the same game also appears with his champ in the same game for the same time. Tried to close and relog but still the same problem. I don't know how it happend, I just clicked Continue when the game was over.
