Issue with Heroic garr and client freezing

Each time I try to login to hearthstone, there is a bug where it takes me to the place I was when I closed out (and I closed the app because it was glitching). I was fighting Heroic Garr in Blackrock mountain with mercenaries with a team of cho/kazakus/azshara/cookie/balinda/ysharjj and when I won the match, the game glitched and froze. So I closed it down, now each time I bring it up, it takes me right back to the spot when it closed and the glitch is.

I tried uninstalling then reinstalling, but no luck. The game is frozen and each time I try to login I get put right back into the glitched area.
