Hello, I have a problem with a custom-made modpack: when I try to launch it in the MC Launcher program, it crashes on "State transition LOAD_REGISTRIES running" - in the lower left corner of the screen it says:
"REGISTERING minecraft:painting_variant" and
"REGISTERING minecraft:worldgen/biome"
it crashes and gives this message: 
The game crashed: initializing game
Error java.lang.NoClassDefFoundError:
org/antlr/v4/runtime/CharStream 
with the Exit Code: -1

 

the crash report looks like this:

If you can help, please respond because I really want this modpack to work, if you can't still thank you for trying, and I hope that this comes to help anyone in the future with the same problem. ❤️

Also i forgot to mention the MC and Forge versions: 1.21.1 - 52.1.1

The config of UnionLib is invalid

Delete the config of it (config folder) - if there is no change, try other builds of UnionLib

Oh thank you, just one more question: How do I access the config folder? (I have never done it before)

The config folder is in the same folder as the mods folder

 

if you are using the original Launcher, then it is

C:\Users\NAME\AppData\Roaming\.minecraft\config\

Thank you very much ❤️

 

I deleted it and the same problem keeps happening

I cannot fully delete the UnionLib mod because I'm playing on a handheld and have to have a controller support mod (it doesn't work without UnionLib)

Did you try older builds?

Trying it right now 👍

Just gotta go back a few versions ;-;

found another fix - in 1.20.1 there is another controller support mod made by mr crayfish

i will respond to this after i try it

ok, so you just have to go back to 1.20.1 to install the mrcrayfish controller support mod and everything will work perfectly
