An unexpected error has occurred. Exiting Final Fantasy XIV

Odd I was getting same error on Battlefront2 and FFXIV, after I did this everything is running fine. Unless you have something conflicting with your system. Sorry was not much help just said what worked for me. Good luck. By the way are you using steam version or regular? I use regular and try to stay away from steam. Seems they have some issues as of late.

Are you under Windows10 too? How did you "uninstall" the DirectX?
If you used the Restore Point method, sadly that can't be done for me, it will just remove the last Windows Update and reinstall it again the next time I update my system (I tried it already) giving the same error again.
I'm using the regular version of the game, no steam attached, I've been reading that the game behaves badly with overlays so I tried to stay away from Steam (also, I bought the game during a SE discount).

Honestly, I tried everything and with FFXIV being the only game on my PC facing this issue, makes me even more confused.

Make sure Game Mode isnt on as well....

This last windows update was wonky for me with my voice/sound settings. Took forever to get it to work again through discord.

Game mode is off! Same result, I can't play in DirectX11 as I've been doing before this WindowsUpdate.

Windows 10 Pro 64bit. Not sure what to tell you then. Other choice is to revert to Direct X 9 manually and re updated to 11. The only other thing I can think of is if your driver and settings are clashing with the system after the update or your port might be a bit damaged or worn. Do you use HDMI or Display port? I had a few crashes do to direct X on HDMI, I switched to Display port and it just happened to me with that "A fatal DirectX error has occurred (10000000)". After I did the update again works fine. You could try that as well.

Uhm, but there is no way to "revert" DirectX on Windows 10, manually... unless you recently updated them and then you used a Restoration Point to go back (which again, I can't use, or the next time W10 updates, I will face the same error) there is no other way to manually untinstall them, DirectX 12 comes together as a package with Windows10 and it includesall the previous DirectX versions already, you don't install them separately, nor you can uninstall them or touch them at all.
If anything is damaged, you run the WebInstaller that should detect any DX issue and repair them, but I have done this first thing and no errors were detected.
I don't understand how you managed to do this under Windows10, unless you used the Restore Point method yourself. :/

About the ports, I tried for the sake of it, but of course it made no difference, it would make no sense, if the hardware was damaged then it would give the same error for every other application, not only for FFXIV... same with drivers, I tried my old ones first, and then the latest, both made no difference, and again only for FFXIV... every other game I have runs with no issues, and they have heavier performance requirements.
