I think what I suggest works for someone who would struggle with discerning between a male and a female (applicable only to binary people, it should be a non issue for non binary ones).

Just use they. Try to remember the gender when told, but if this is still an issue, use they (for the names, I just find workarounds to not have to mention them when I can help it).

(especially in English that seems more and more current; in French iel is becoming more common but still not very widespread)

Surely people can understand and accept your struggle if you explain what's happening, though again, I never met someone like this knowingly, so I can't be sure how that works.

You're too ahead of your time! :-)
