Error 1012 and 5006 popping up, game ran perfectly fine before this error

Update disclaimer

• [X] Yes, I have checked and my issue is not related to the game updating and plugins not working correctly.

What did you do?

So I was logged into the game like usual, clicked start expecting to see my character, only to be greeted with error 1012 and 5006, despite my game being up to date. I tried witching data centers, and even tried restarting my computer a couple of times. I tried everything from repairing game files to even using the game's actual launcher itself, and still I somehow get the same errors each time.

Below is a screenshot of the error, I mostly got 1012s and couldn't get the 5006 in time

500X errors mean the login session is expired. 1012 can also show up from that sometimes, like if you've managed to launch a client that is out of date. (Or claims to be).

First, I'd recommend making sure the UID cache feature has been disabled or reset.

On Windows, you can reset the UID cache by holding down the Control key on your keyboard while opening XIVLauncher. Or you can make sure it's unchecked by going into XIVLauncher's settings -> About tab -> Advanced Settings section.

That said, the log snippet you've posted above indicated hard disk failure. Cyclic Redundancy Check (CRC) comes directly from the disk/ssd controller and means the underlying data is corrupted. It is not fixable. some disks will mark it read only or try to block reading from it entirely to prolong good parts of the disk, but you should backup your data and move it elsewhere ASAP.
