Yeah, I’m thinking it’s an issue with new accounts. This happened to me earlier when I wanted to start a ranger because I only have one of my four slots filled with a character. I tried everything from updated to downgraded drivers, ran the repair, tested EVERY SINGLE resolution, changed settings to minimum, maximum, and even tried doing it on my laptop(and yes I tried restarting). Nothing changed. So I asked my friend who had recently bought the game when it was on sale like me if he could crate a character, and nada. So then I asked another friend who recently started and he too couldn’t create anything new. After realizing the common denominator of everyone being new I asked one more person who has had an account for a year+ if he could do anything, and wouldn’t you know it he could create one(or that’s what he told me at least).
