Unable to Connect to Game

After successfully connecting to champion select, champions are selected, and the game starts, but the client immediately crashes and is unable to reconnect no matter how many times I restart the launcher or click reconnect. This bug happens seemingly out of the blue and I'm not sure what causes it, but it prevents me from playing for the entire game. After the game concludes, the client reconnects to the normal post game lobby, where people get mad and I have to apologize.

Edit: It's now happened to me twice in a row, so rip. 2nd Edit: It's now happened a third time, and I've restarted the client twice between connection attempts. 3rd Edit: 4 games and I still haven't been able to play, I restarted the client multiple times between the 3rd and 4th games, and I restarted the launcher both normally and as administrator. Neither worked and I was once again unable to connect to the game. Final Edit: I was finally able to load into a game. I just needed to restart my computer a few times.
