Thank you for the reply JebiSe.

The error you are getting is a generic crash error. It's saying that the game is unable to continue operation and needs to close. This can happen for several reasons and it can be difficult to pinpoint the cause. There are several other threads about this issue because it is the same message regardless of the source of the issue. As such, there can't really be a "fix" to resolve every computer that crashes unfortunately.

There are a few other that may help alleviate the issue:

1) Disable all unnecessary programs running in the background. Make sure to disable all overlays as well (Discord overlay, Geforce Experience, etc.).

2) Set compatibility mode to Windows 7. Right-click on the ffxivboot.exe file and select ‘Properties.’ Then select the ‘Compatibility’ tab and choose Windows 7.

3) Do a clean reinstall of your graphics card drivers.

4) Reinstall the game. Make sure to also remove the locally-saved data folder (located My Documents > My Games > Final Fantasy XIV). Make a backup of this in case it doesn't resolve the error.

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