PBE game not starting Patch 8.8

Hi,

It started yesterday 04/03/2018 around night time NA server PBE. I had few games started normally in "All for One" after a game had ended and I started a new one it went on smoothly in the banning and champ selection screen until the game is about to start. The Versus screen didn't appear and all I hear is an "Error windows chime" no bugspalt notification or whatsoever. I tried to use the repair tool and repatch the launcher but still, it doesn't work. Today 04/04/2018 I tried launching the game and played in the practice tool it went without a hitch. But after I tried joining a game in "All for one" it went smoothly from the banning phase to champ selection and after that still, I get the same error as I mentioned above. Any help is really appreciated.

Thanks, :(
