[CRASH/MEMORY LEAK] Game Freezes Randomly

At first I thought it was strictly a bug that happened with my first game of the day, so I usually go into a co-op vs AI and experience there before I go into solo queue. I went into a normal 5v5 Draft game (avoiding Ranked when I believe this issue will occur) and it happened in the middle of the laning phase. The occurrence is limited to the load screen getting to 100% as well as any point in the game regardless of what may be happening.

Upon going to Task Manager, League of Legends jumps from its regular memory usage to over 1-2 million bits. Nothing in the game is responsive and after going to task manager the screen is stuck on black, no sound is played.

Reproduction of the issue is impossible as it seems to be awkwardly occurring. Prior to this moment I had played a game of with Corki which had no issue. I believe it may be linked to those that were having game errors and crashes, or an interaction with TFT coding being implemented as this only began for me after the game mode was introduced. Maybe it's client side, or an interaction of user programs.

Given the number of users affected, I believe it would be within Riot's best interest to find the players on the forums reporting such leaks and giving us some tool to help you gather information for a possible common symptom of all our computers.
