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

Please try the following:
- Update and reinstall the drivers for your graphics card and sound drivers (if applicable). For your GPU [AMD Radeon RX 6600] it appears that the driver was last updated on [3/29/2023] which is quite outdated. Please double check that the GPU driver is updated, this cannot be done through the device manager.

- 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 as installing the game on other drives may lead to unexpected errors.
- Please be sure to disable or remove any overlays (Discord, Steam, NVIDIA etc.) as they may interfere with startup. It appears that you may have the program [Friends - Discord] running in the background, for the troubleshooting phase please close this program.

- Make sure that the Windows OS is fully updated.
- Reinstall game

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