    as I have never used it I cannot tell you why it is happening but I can tell you what is happening. There is a mod called Mixin that is erroring out, not surprising considering the purpose of Mixin is to let you run other version mods on Minecraft. ex. 1.8 Minecraft with Mixin can run 1.7 mods. attempt to get the game running with only 1.19 mods and get rid of mixin

    Went to the CurseForge discord for this one, try completely (Programs and Features) uninstalling Java 20 or any other version. It needs to be run on EXCLUSIVELY JDK 17.
