Greetings, thank you for posting in the Final Fantasy XIV Technical Support Forums.

We apologize for any inconvenience experienced when trying to play Final Fantasy XIV. Please try the following:
- Switch between fullscreen and borderless windowed modes.
- Update and reinstall the drivers for your graphics card and sound drivers (if applicable). Should the issue persist, please try a clean reinstall instead.

- 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 that Final Fantasy XIV is installed to the C: Drive.
- 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.

Upon further review, it appears that you may be using Windows' cloud program 'OneDrive'. Please try disabling this program as it may cause interference as it tries to sync your files. Additionally, it appears that your system may have two GPUs. Please make sure your system is defaulting to the correct one when accessing FINAL FANTASY XIV.

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