Mixin is agnostic to Minecraft version.

However, you seem to be asking for help in the wrong place, this forums is for the Sponge server software - which your issue is not with.

Try removing optifine and optifabric, optifine doesn’t like mods. I’ve tried putting it in modpacks and it always breaks them

Thank you so much Techno_the_Protogen :smiley:
In my case it’s sodium that made my game crash and display this error

I think it’s because of cloth config

btw version is 1.16.5

That sadly doesnt help.

Best of creating your own issue as sponge has a lot of different errors due to Mixin Errors. That being said, 1.16.5 SpongeForge is not stable yet so a lot of mods break it currently.

But would still be good to know what and how
