Playing on a 1.19.2 server. There is no prosperity ore generating in the end. Tore apart a whole island and found nothing.
I checked the settings and see that its set to spawn in the world but nothing exclusively for the end if that's required.
Playing with version 6.0.3

Do you have Mystical Agradditions installed? Nether/End Prosperity Ore is added by it.

I did not, that fixed it. Thank you.
