With fortnite construction settings there's always a graphic error why?

So if I want to change my editing setting on fortnite I always get an error message. Can you please give me a few tips on how I can fix it

What if you press yes?

It sticks to yours and if I press no it goes back

Restart the game and console.

Still works nt

If you just press no

Then he goes out and when I go back in, the same thing happens
