The compiler seems could auto load the MixinConfigs in the version below 1.20.6, but it didnt work from 1.20.6. I just modified the jar file to zip and found the META-INF/MANIFEST.MF is lack of "MixinConfigs" compared with the lower version, while the build.gradle are same. So I manual added it to fix the problem. I dont know the implmentation of this process, but a different is in 1.20.6 the jar task deleted the reobfJar task, maybe this leads the problem?

Try modify the build.gradle by: 1. Add 'MixinConfigs' : "${mod_id}.mixins.json" to the attributes array tasks.named('jar', Jar).configure { manifest { attributes([ .... ]) } } 2. Add a new block after the mixin block sourceSets { main { ext.refMap = "${modid}.refmap.json" } }
