Game crashing, no error

this is the 3rd time my game has crashed in a ranked match, resulting in a loss. the game just closes. my screen looks like its tabbing out of the game, but the game just quits.

what can i do to get a log of this happening? i have a video of my last match if that helps.

this will never happen, but can i get a refund on those 3 losses? i would be 36/6 if they would have never happened…

youtube of last 20 seconds of last match with unexplained crash. please note that gameplay was not choppy, OBS was dropping frames for some unexplained reason (the first 2 crashes post hunt 2.0 were without OBS running):
