I trying to play neoforge on minecraft to try create aeronautics so i set up my new modpack that i set it up and on some missing and updating mods normally game loaded only into menu, but when i create word but, when i was in the loading screen just about to load into world it start saving my world and crashing, i tried multiple things to disable delete adding and more, after i turn off sodium, game load into world, embidium didn't work bcs veil doesn't work and more but i will link here my log, for modpack to actually test it contacted me throw dms forum

Error: org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered Log

The link to the log is wrong

Log
should work right now it will download that log text file

Does it work without Iris?

nope after turning off iris shader still doing the same problem it only works if i turn off sodium world will load up, i think there is mod i download that have some conflict between two or multiple mods, idk what mods doing this bcs when i create new modpack only sodium and iris shaders game loaded and world too

Maybe some sodium addons (sodium options api etc)

i have only sodium and iris any addons i don't have

Try other builds of these 2 mods

like turning off both of them? it works without them

i send you my modpack into your inbox

Check for updates of these 2 mods - maybe there are newer 1.21.1 builds of these

Nope still same problem
The game crashed: unexpected error Error: org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered

Does it work with only these 2 mods, without an other mods? If yes, add the rest of your mods one by one or in groups

it works without sodium and iris shaders

okey so i just test it that i only turn off all mods and only left sodium and iris shaders and it also doesn't work

Delete the config files of these 2 mods (config folder) - if there is no change, use a pre-configured mod pack with these 2 as working base

alright can you look on it? i need to leave for 2 hours atleast you can understand the problem and then i can fix it with your instructions, bye for now i will be back in 2 hours or less

My attempts
1. I delete all config of the sodium and iris shaders (Didn't work)
2. I delete all config of the sodium and iris but i turn off both of them (It work)
3. I turn on sodium and iris but i turn all mods besides sodium and iris (Didn't work)
4. I delete entire modpack files besides mods with only on sodium and iris all mods are off (Didn't work)
5. I delete sodium and iris shaders reinstall it and delete all files besides mods onl have on is sodium and iris shaders (Didn't work)

Does this modpack work?

https://www.curseforge.com/minecraft/modpacks/distant-horizons-iris-shaders

Yes it load it up

Use this as working base and just add some mods

Okey when i add only two create mods and are they Create and Create aeronautics modpack shows that all mods are not up to date, the modpack you gave me i didn't update it i just leave it like it should i update it to all newest versions of those mods?

The latest Create build may not work with Create Aeronautics

wait so all the time it doesn't work bcs the create and create aeronautics don't work together?

They do work together - but not all builds are compatible
