I have near 700h of DB, I recently upgraded from Win7 to Win10 (pro 64) and that's when this problem started.
I'd launch the game, EasyAntiCheat splash screen shows up and loads and then nothing.
During this, Steam indicates Dirty Bomb is running then disappears.
Sometimes there are 2 processes that are stuck, EAC and Dirty Bomb, sometimes it's EAC and EAC launcher (which seems to be wrapping DirtyBomb and a COM process)
If I repeatedly try to launch the game, I get a EAC error 3005 (I'll add a screenshot when this happens again). If I reach that point I have to reboot because EAC is stuck on that error.
If I don't reach that point sometimes the game will launch but it's way too random at the moment. Last night it took me 30 minutes and a few reboots to successfully get into the game.
