[Gameplay] Yasuo game-start freeze

Every time I pick Yasuo to play in Custome and Normal games, the game freezes at the start.

This is how it happens, and it happened every single time so far, so it is a granted thing rather than a chance:

1. Open client, log in. (everything is fine)

2. Create a game (Normal or Costume), and choose Yasuo (regardless of skin, or summoner spell). (everything is fine)

3. Load Screen. (Everything is fine)

4. Load Screen finishes, and I see the base, and music playing in the background. (game froze) (time 0:00)

If you open Task Manager, you'll see the client"Not responding".

The only way to continue playing the game is to force closing it (Ending task in Task Manager), and then opening League of Legends client again and reconnect to the game.

This makes you miss almost 2-3 levels in lane.

I tried to re-install the game, and fixing it, but no use.

Please Riot, fix this.
