game does not launch

[MinOfForest]

Same problem here. Launcher opens normally, checks login/password and updates normally, but when I click "Play" it opens a new window, both windows close, and that's it. No error messages.
I don't see any logos, options, nothing — the game window just opens completely blank (black) and closes half a second later. I don't even get to see it impacting on the cpu usage.
This started after the Dawntrail update, it worked normally before.

I'm playing from Steam, on Windows 10, using NVIDIA GeForce GTX 650.
I have tried restoring system settings and restoring game data (from the Launcher). Have not tried reinstalling the whole game yet.
I've also tried updating my graphics card driver (nvidia geforce gtx 650), with seemingly no difference whatsoever.

Does FF14 create any log file, anywhere? Couldn't find where one would be located. Is there maybe some config file option to force one to be created?
Thank you.

Exact same issue here. Log in just fine, click "Play", game screen starts to launch, but disappears along with the Launcher while it's still black. I was able to play just fine until the servers went down for patching.

I've tried: Removing and reinstalling the game, updating Windows fully, "Reset System Settings" x3, "Restore Game Data" x4, updating graphics drivers, restarting the computer a million times, copying /boot folder from a friend, disabling "Game Bar" since that was in my Event Viewer logs, temporarily deactivating Windows Firewall and Defender (apps are whitelisted anywho). I'm at a loss of what to try next. I've been doing the Restore on loop in case that gets lucky, but so far no dice.

Windows 10 64-bit, NVIDIA GeForce 680, Windows install (not Steam)
