Issue with DirectX 11 since Endwalker update.

[Puss_Kat]

Historically the Green screen is linked to Radeon crashes where the driver is applying insufficient voltage and the GPU crashes into protect mode,

The game crashes right after I click the green Play button on launcher, I can't select DC, server or character, just a black screen with one or three error messages about dx11 and game crashes.

This sounds familiar, is this PC upgraded from Windows 7?

I encountered the same on a such a PC where prior to the upgrade it worked fine, it turned out that part of the DirectX 2010 runtime was removed during the update and the Webinstaller at the time was failing to correct the matter, running the full june 2010 package did the trick.

Download, run it (extract to location), go to extracted location and run dxsetup.exe

Other reasons for a crash prior to the menu would be corrupted data in the sqpack contents, poor mixing of overlays, outdated reshade dll, Nahimics overlay server.
