The dxgi relates to a graphical issue, mitigated it by disabling a 3rd party overlay (overwolf). Might help you guys but I'm not sure.
Sauce:
0x00000001 – UNABLE_TO_INIT_DXGI
The game is unable to initialize a graphical subsystem. Possible solutions:
Update the graphics card drivers to a newer version.
Rollback the graphics card drivers to an older version.
Check the temperature of your GPUs and CPUs.
Disable the Steam Overlay.
It's not the same error but dxgi stands for directx graphical interface
