Is this on a fresh install or are you trying to test a mod you already created? Did you update from a prior build? Did you update manually or through the launcher?

Gigant_Character_BP_C is the problem
user the other one. BASE, let me know if it works for you. Your NPCSpawnVolume +Count Only should be other other gigant, not that Gigant_Character_BP_C one.

fresh install.
i mean

  1. download epic games launcher, and install
  2. download ark dev kit, and install(through the launcher)
  3. push play button
    then “Assertion failed”.

I already tried re-install 3 times.

oh, thank you man! I can play. I tried force delete Gigant_Character_BP, and BASE.
play is working fine now:D

Glad i could help.
You dont have to delete the asset, just remove it from your map lol

I will try it again. re-install now.
If my memory serves me right, even it occurs if map is empty. so always.

hmmm, something is wrong with the asset then. the issue would be specific to your machine.

It still occurred after reinstall, but I found how to temporary fix it.
just open ‘Gigant_Character_BP’, ‘Gigant_Character_BP_Base’ and close them. then I can play!

I need to do that every time. why? I don’t know!
but I can play all map now! smallIsland? yes i can. theIsland? omg yes i can.
yay!

I found this thread. same error.
something is wrong, i think so too. but noidea!

all i can think of is to delete the assets from your machine, then, do a “verify” and let them download again.
I am having issues with the jungle clutter layer only. For some reason, the meshes are distorted. I dont know anyone else having the issue. I never touched them. Strange things …

“verify” didn’t work for me. assets vanished.
i will try english version!

“Edit” -> “Editor Preferences” -> “Region&Language” -> “English”, “Non-Specific Region”. and restart.
play will work normally.

I’m tired…
