Repeated Client Crashing

Ever since the Riot client issues, my client randomly just stops working and crashes as seen from the link. Nothing causes it, I leave my client idle, I can go into queue, doesn't matter, it crashes no matter what. This issue has caused me to disconnect from 4-5 different Draft Mode champion selects, and I'm sitting at a 15 minute wait time each time it does this. This is also in addition to the chat login errors, and the server disconnects. I've tried repairing my client, and nothing has been fixed. A few of my friends have this issue, but some have no problems at all.
