Hey there 
Since yesterday in the evening my game (and recently also Launcher) Keep crashing for no know reason :/.
It all started like this: after a couple of games yesterday (29.05.'17) I had to leave my last game (poor sportsmanship I know and I’m sorry) as I came back in the afternoon and started another round with 2 friends the game crashed after loading Monolith. I had like 20 seconds ingame. I tried to reconnect serveral times but after just a few seconds the game crashed again. in the Report are no causes listed.
I reinstalled the game and after realising it hadn’t got any better also the launcher plus the game again.
As I tried to find a solution in the Forums I still have no clue why this is happening.
my DxDiag: link text
I cleanse my Laptop just 2 weeks ago and didn’t had any Problems beforehand yet after I watched for a new BIOS Version for my Laptop (there ain’t one) and test other tipps from the Forum I restarted the Launcher and the game many times. Now I can’t even open the Launcher anymore 
help is appreciated and have a nice day
