Draft Pick Champion Select [CRASH]

This has been happening quite a lot recently. The Draft Pick champion select menu tends to crash at random times, sometimes blackscreening, sometimes just becoming unresponsive. It usually happens when me or my friends press a button in the window, and happens to about half of our games. I've seen a lot of other threads about this issue, and it's starting to ruin the game. Just now, me and two other friends all crashed at the same time, and we all got cooldowns. Please fix this.
