Errors in currently selected datapack prevent the world from loading

[JoshN]

Hi, I've been playing on a custom modpack for nearly 200 hours now and ran into an error.

Note: This isn't the exact screenshot from my game but this is the exact error message. 

I was attempting to add in a block called magical soil (a part of the allthemods modpack) which said it originated from the kubejs mod. I copy pasted in some files but it never showed up so I replaced the whole kubeJS folder with one from the ATM9 modpack but this created a bunch of errors because of missing mods so I tried restoring the old folder. The game doesn't crash anymore but it gives me this "Errors in currently selected datapacks" message. 

I tried renaming the level.dat_old file to level.dat as some people recommended but this didn't help at all. I noticed some mods were missing but even after adding back in the ones I saw the error persisted.

 

Edit: Pastebin Files

The log files is quite large and I have no idea how to read it, had to cut it into 2 parts:

Crash Log 1

Crash Log 2

When trying to create a new world the game crashes before getting to the screen and gives the exit code -1 and this is the crash log

World Creation Crash

I had the same issue when I was making the pack and I eventually solved it by removing the mods that were conflicting/crashing but I suspect that this wouldn't solve the issue with the already created world. I was thinking that maybe the issue was a mod that accidentally got disabled/removed but I'm not sure.

Please read the FAQ on how to post your logs; embedding them in your post like that makes them very hard to read, which may make it harder for people to help you.

I'd be interested to know if you run into the same problem(s) if you create a fresh world, vs loading into the one you've been playing.
