matchmaking freeze every 1 of 20 games

Hello new Matchmaking screen is regularly freezing on myself and many of the people in the exact same game,

I do a solo q write down a few of the joined players names in the game that i saw when the game froze

messaged the players and they all said the same thing

champ select screen is freezing right away on 1 of 20 game average AS SOON AS THE LOBBY OPENS

it says players have joined, the room and then boom nothing happens.....get booted off the game and log into an huge leave buster timer

this happens to me almost every single day, at least 1 time sometimes 2 times only with the new matchmaking
