Make sure your BIOS/UEFI is up2date from your mainboard manufacturer. Remove Tools like AMD Ryzen Master, they may write some unwanted settings to UEFI.
I removed AMD Ryzen Master, and uninstalled FFXIV. I'm currently reinstalling it now. If the error occurs again, I'll flash my BIOS with the new version.
