[CRASH][CLIENT] Bugsplat/Repair issues

Okay so this has been happening since I downloaded patch 6.4. I'm not sure what the problem is what so ever. I've re downloaded the entire game and deleted the temp files and everything. I've tried repairing through the client multiple times and nothing works. I will post logs below, but a short description of the problem is basically this,

Since I downloaded patch 6.4, it worked for like two or three days and then I got a bugsplat and the game crashed. I exited league and upon opening it back up I was encountered with a repair message and continued with it. Sometimes the repair would complete and I still couldnt join the game, sometimes the reapir would fail and then the client would randomly start working again. Recently after the fresh install it work for a couple days and then I started having the problem again, but this time sometimes just upon opening the client it would ask for a repair (w/o any crashes or anything) I would reapir and it would work fine.

*One thing I've noticed is it tends to happen when I try to play bard, but again sometimes it works.
