R6S client crashing without any errors.

today i logged in to play a game or two and while i was in the prep phase my game crashed out without any crash reports or anything. after that i started the game again and it was fine till the 3rd round when in the prep phase the client crashed again, without any of the reports or send crash report dialog box. i have verified the files from steam client but that did not do anything to help the problem. It's really frustrating crashing out in the middle of a game that too thrice.
