Game and Client Randomly Close [CLIENT]

This is going to be a fairly brief post. Since the previous patch, the game and/or client will just randomly close. There are no bug splat reports nor any obvious reason for it/them closing. This has been happening both ingame and inlobby, both just acting as if I had closed the game manually. The processes disappear from the Task Manager, and it's just frustrating to deal with. It has been happening somewhat frequently. It happened three times in my last game last night, and it happened once while waiting in a lobby today (just a few minutes ago). I don't have any screenshots or proof of these occurrences, so there's not much help to be had there.

Thanks for any input and feedback to help with this. I will answer in kind.
