DirectX 11 Errors

[Fyoooh]

Following my first post, I've tried some manips to see if I was still crashing :

- Video card reinstalling with Display Driver Uninstaller : Crash,
- Game reinstalling : Crash,
- Unplugging all my devices and switching off bluetooth : Crash,
- Deactivating Windows security system : Crash,
- Synchronizing graphic card parameters in Full HD 1080p in 60Hz and 75Hz in Nvidia Config : Crash,
- Deleting and reinitializing FF14 config files in My Documents > Games : Crash,
- Tested in 60, 75 and unlimited FPS in FF14 config according to Hz : Crash,
- Changed install folder from my External SSD to my internal HDD : Crash,
- Switched back to old launcher : Crash,
- Tried to enter in the raid in both DF and PF : Crash,
- Tried in windowed, windowed without borders and full screen modes : Crash,
- Tried with and without my monitor : Crash,
- Did all my Windows updates : Crash.

Only thing that changed after reinstalling the game was I am now crashing without the above-mentionned error pop-up, loading screen is now freezing then back to desktop.

If anyone has another ideas excepting buying a new computer, that would be nice... !

Following this previous post I've tried some other things :

- Downclocking GPU with MSI Afterburner : Crashed,
- Custom 3D presetting FF14 on Nvidia Control Panel using Fixed refresh rate and adaptive V-Sync : Crashed,
- Tried Kejoca advices by using W8 compatbility on launchers and FF14 DX11.exe + Admin : Crashed.

However, I've had some "new" error popup window which mentionned d3d11.exe errors instead of dx11.exe ones. I've tried to disable Direct 3D Acceleration cause I remembered having issues with it when I was on W7 for some old games but it doesn't seem to be possible on W10...

Now I'm going to try something absolutely stupid but if that works, I'll laugh very hard (Uninstalling my GPU driver and install the oldest one I can find (2017). I'll post the result when I'll manage to find a Copied Factory party... (Probably tomorrow or tuesday) so if someone wants to try before, he's welcome to !

EDIT : Crashed with the oldest driver but had a new error message + Game redirected me on main screen config system when trying to enter in Copied Factory - https://imgur.com/a/4dSKMse

Retried with MSI Afterburner - https://imgur.com/a/R0a6x3z As you see, the loading page is frozen but it's actually redirected on main screen system configs as well.
