I had the exact same problem. Restarts didn't work, fresh installs, repairing. I luckily found someone in the anthem discord that got help and said it worked for him, as did it for me, and hopefully for you. Simply go into the game, settings>video>Adv. Graphic settings and look for 'texture quality' and 'mesh quality'. Change those to medium, save settings, restart the game. Once u exit anthem and restart it worked for me. Best of luck and again hope it works for you too!

Yesterday I changed back my Mesh Quality setting to low (it was part of setting everything to medium or high in the graphics settings workaround) and everything seems fine. I guess maybe the Texture Quality might be the real culprit.
Yes I have that right now and it makes the Cataclysm unplayable which is very very disappointing considering its ending soon.
