Before anyone states I should try going back to the stable build, I've tried about 4 of the builds, including the stable one and the same thing happens on all of them.
After anytime between 5 mins and an hour (I played for about 3 hours last night and it didn't happen) the game freezes. My computer doesnt crash, I can still alt tab and force the program close, but the ui and the game freezes. It doesn't appear to have any Rhyme or reason, but I have to force quit the program and restart it. Even if I wait 20 minutes the game doesn't "crash" - the UI just remains frozen.
I created a mini dump of the game whilst it was frozen:

I also have this windows version: Version 1151 (Build 10586.545) I updated my GFX drivers last night so it's not that.I have 8 gigs of ram on an i7 4790 using an EVGA 970 OC. I don't have EVGA precision running (I've checked services) and I don't have any other major software running I do have anti virus (Avast Free) but I have that on Gaming mode.
Any ideas?
