1.20.1 "Critical error" crash while initializing a 1.20.1 modpack

[TPG]

Hello, I tried playing a modpack I made (I'm not very experienced in modpack making) and, except some problems I achieved to solve, everything went good. However, when I recently tried to re-test the pack with new mods my game crashed. All the changes happened in the span of a noon tho so I barely know which mod were added and when exactly.

 

Here the error :

The game crashed whilst initializing game Error: org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered

The pack is forge 47.2.0 for minecraft 1.20.1

I use Rubidium+Oculus and also Valkyrien Skies. (i list them here since they're often buggy with other mods)

 

Here the entire crash log :

I hope someone can help me and thanks.

Create a new instance and start with Embeddium/Oculus and Valkyrien Skies

Try different builds of Embeddium/Valkyrien Skies until you find a working combination - then add the rest of your mods one by one or in groups

Ok, thank you! I'll try this

I tested it and apparently the problem comes directly from rubidium/oculus and Valkyrien skies, they're not compatible in 1.20x... I'm maybe going to fabric then since optifine doesn't work either. Thank you anyway and have a great day!
