As per the subforum rules, I am posting here to state I also have this issue, with only one solution: If I click "Play" in the interface of Nvidia Geforce Experience, the FFXIV Launcher will allow the game to open. If I attempt to play the game without using Nvidia Geforce Experience, it does not load and I get the 6d error. I do not have any issues with overheating or storage space. I have never installed MacType. I do not start the game with any gamepad peripherals plugged in. I have attempted all other troubleshooting suggestions from support staff in various forum threads with no fix.
