Posting here because I also have the same issue, and everything I've tried on multiple forums don't seem to work.

Things I've tried:
  1. Clean update of graphics card drivers (Uninstall with DDU before re-installing)
  2. Updating chipset drivers to latest
  3. Unlocking my frame rates
  4. Setting graphical settings to highest/lowest
  5. Turning off various overlays (GeForce Experience, Discord)
  6. Disabling Microsoft Game Mode
  7. Disabling DOCP/XMP via BIOS

The only thing that seems to work for me (once) was reinstalling the game. FFXIV won't crash during that first launch after reinstalling. It's really disheartening to find that your subscription has gone to waste because you can't play.
