AppCrash and BEX when playing Dota 2

[Animate]

Hi guys. I've recently installed Dota 2, and with my first four games(around 9am in the morning), I have not experienced any crashes. When I played again around 11pm, the game crashed repeatedly. I can reconnect to the game but after a few minutes it crashes again. I've also experienced AppHang, AppCrash and BEX error.

I can't attach the minidump from Steam because its around 1.16GB each. Any help would be greatly appreciated.

I've managed to get the log when it crashed when I tried playing again.
