Version: 1.20.1

Forge

PrismLauncher

I added a few mods, AcceleratedRendering, Bumblezone, Spud’s Shops, Sophisticated Storage and Spice of Life: Carrot.

SophisticatedStorage needed a newer version of SophisticatedCore, so I updated it. Then, when loading again, it said it had an issue with either Opposing Force, Fusion or a Fabric loader (not sure what.)

I turned off all of the new mods I added and that fixed the issue, but when trying to load my world, I was hit with ”Errors in currently selected data packs prevented the world from loading. You can either try to load it with only the vanilla data pack ("safe mode"), or go back to the title screen and fix it manually"

Loading in safe mode did not work.

I tried to rename the level.dat_old folder to level.dat, it didn’t work. I tried to replace level.dat_old, level.dat, and session_lock with the same files from a new world loaded with the same seed, didn’t work. I tried to do this again but with the region folder instead, didn’t work. I do not have a backup.

I don’t know how to edit NBT data and I’m incredibly worried about losing my world, but I understand if this is impossible to fix. I never loaded into the world with the new mods installed and enabled and have not generated new chunks.

Here is the log:

Does it work without terrablender?

I disabled Terrablender, but it's required for Biomes We've Gone, so it crashes without it enabled
