org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered 1.20.1


Recommended Posts

I installed forge and few mods, created a world and everything was doing okay then few hours ago I wanted to add more and got four that is diagnal fences, suplementaries, mcw lights and sophisticatedbackpacks. When I was loading the mods one by one I noticed that a MixinExtras thing appeared (which I believe was not there when looking at the mod list in game but I could be wrong about that) and then when I tried loading up the world that I modded first I had an error. I reinstalled forge, reinstalled mods. I can generate a whole new world and everything works fine but that one specific world. First I had put all of the libraries, installed some more, then added mods and still I can't load that world. I don't know anything about these things and I don't know what to do. Is there even anything I could do or is it a lost cause?

Edit: Nevermind, I have access to the world. Some of the mods libraries that I was adding were also adding the MixinExtras that were causing me not being able to load the world (it was loading but immediatelly saving). I went through the mod list again (installing, reinstalling and adding again and stuff) and the MixinExtras were also there but this time I can access the world. I have no idea what is causing this but going one by one and testing helped. I removed Moonlight, Architectury and DoApi and that were causing the problem.

Crash report:

Found the solution to enter the save, although I'm still confused and hope for a solution to add these other mods.
