In game picture:

maybe it's compatibility issue with other world generation mods, it would be helpful to find out with which and add some sort of compatibility.

Did you add one of the Lost City addons? Or is Lost Cities itself the only Lost Cities thing? Can I see the entire latest.log?

i installed Keerdm's Zombie apocalypse essentials

Here the latest log where the error in the issue poped up.

i deleted it and now mod is working correctly 😅.... That was awkward.

That's a common issue. You just need to select the world style "keerdm_zombie_essentials:testworld" when customizing the lost cities, and it will work.
