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

I apologize for the delay in our response.

The error you are experiencing is a generic error, stating that the game could not continue to operate and thus closed. This can be caused by a multitude of things, making it difficult to pinpoint exactly where the issue stems from. This is also why this error is so common, different causes will end in the same result.

If you are experiencing this, I'd suggest trying the troubleshooting listed here: https://sqex.to/yHxyN

Unfortunately, since every PC is structured differently there is no single step that will fix every issue. As such, we'd recommend attempting all of the troubleshooting above.

Thank you for visiting the Final Fantasy XIV Technical Support Forums.
