Have you tried turning down your settings to the lowest possible settings and tried starting up? You can do this by selecting "Options" on the launcher and turning everything down.
Have you run the fullcheck.bat
file in your game folder? You can find this at the directory C:/AeriaGames/EdenEternal.
You can try doing this fix
if the fullcheck doesn't work. It hasn't seemed to work for everybody, so it's hard to say.
Have you tried reinstalling? You can try reinstalling from a mirror
to see if it stops the issue for you.
Let me know if any of these help you out.
