Good morning! Thank you for posting in the Final Fantasy XIV Technical Support Forums.

Please try the following:
- Please try switching between Fullscreen and Borderless Windowed modes to see if it helps with the issue.
- Please try adjusting/lowering the resolution.
- Please try running the game as an administrator.
- Perform a clean boot by opening the task manager and select the 'Start up' Tab. Disable everything.
- Please be sure to disable or remove any overlays (Discord, Steam, NVIDIA etc.) as they may interfere with startup.
- Make sure that the Windows OS is fully updated.
- Reinstall game

- If you have additional peripherals attached to your system, please try disconnecting them until only the necessary components are attached (mouse, keyboard, and monitor) for testing purposes.

When the issue occurs, are you able to close FINAL FANTASY XIV without causing your system to freeze?

Thank you once again for visiting the Final Fantasy XIV Technical Support Forums!
