Problem with datapacks (safe mode - title screen)

[Warplord]

I am trying to play a pack Create flavored with a decent amount of added mods. I create a worlds but when I try to enter it again it gives me "errors in currently selected datapacks prevented the world from loading" and it gives me two options safe mode and back to title screen when i click safe mode it does absolutely nothing.

 

Here is a pastebin of the log which i think is relevant? https://pastebin.com/Ggme0Fbp  If not - please tell me where to look for clues what the problem is.

Seems to be a problem with Ida's Structures.

Thought so too - removed it - issue still persists. I can create a world but when i log out i cnat get back in.... how do i disable datapacks and stuff ? All the folders inside the modpack folder that say datapakc or texturepack etc are empty :?

You might have to go into the datapacks folder of your world and remove it manually. If it is doing this to newly created worlds, I you need to manually crash the game (F3+C for 10 seconds) and send the full debug.log.
