Unexpected Error: ffxiv_dx11.exe+300C09

[Lilael]

Recently I did a clean install of OS Win 10 after upgrading my graphics card and RAM. I did this 11/26/18. Then I reinstalled FFXIV and I keep getting these errors ever since:

I can be standing in the game not moving, just redoing my HUD, and after a period of time it will happen and close the game.

I used to run fine with no issues, but before the changes I made on 11/26/18 I had Win 7 and a GTX 760 with 8GB of RAM. I've done a clean installation twice and this is happening, a no amount of reinstalling my drivers or updating Win 10 has helped.
I'm not sure what is wrong, and I'm not really skilled with computers in the first place beyond what Google can tell me.
So here's my current system:
CPU: Intel(R) Core(TM) i7-4820k CPU @3.70GHz
GPU: ASUS GeForce GTX 1070 8GB
RAM: 16GB
OS: Win 10 Pro 64-bit (10.0, build 17763)
DirectX 12. My drivers are up to date according to device manager and GeForce.

Any help appreciated..

I was able to go in game, redo my BRD hotkeys, do a Nidhogg EX run, and then exiting the Nidhogg run the game got another error.

Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

You mentioned that you upgraded to Windows 10, correct? If you install Windows 10, it won't automatically install the 'Optional' and 'Recommended' updates. Makes sure these are updated if you haven't already.

Does this same error occur when using DirectX 9 mode?

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
