Hello. 
Try to reboot your PC in safe mode and afterwards restart normally.
Here is a guide for Windows 10 if you don’t know how:

If that doesn’t fix the issue please follow the instructions of the first post in the following thread:
Good luck!
I have the same problem, yesterday I’m playing just fine.
When I try to launch it, it goes to the splash screen with loading, and after a few seconds it never launch again.
I suspect 2 things :
Please help anyone, this is my favorite game 
I got the same problem
Edit:
Ok, I just simply restarted my computer. And then when starting steam it updated steam itself. Then tried starting DB and it starts fine now…
I dont understand but happy it works again
I’m getting the same issue. But none of the fixes here help. Tried, verifying game cache/integrity. Running EasyAntiCheat and selecting DB. I tried running Steam as Admin and the memory CMD command.
I still get nothing after seeing EasyAntiCheat try to load.
Most games I have that use EasyAntiCheat are not functioning. But also Warframe stopped working same exact day/time. No changes to my system
FIXED!
It was my USB NVIDIA SHIELD gamepad. Had only recently been using it for the Tekken 7 release. Unplugged it and have been golden since.
Interesting enough. This fixed Dirty Bomb, Warframe launcher, Keystone Alpha launcher, Ghost Recon: Wildlands and Tekken 7.
Plugging the controller in after game launch, seems fine. But before is all bad and definitely can’t boot computer with the controller plugged in…
*NOTE: Using my Acer display as a usb hub. I will try direct connection.
