      Crash at launcher issue

      By GenChicky · Posted

      I made a custom pack, but i can't even load it, it just crashes at launcher, giving me Error 1. I looked at the log, and it just doesn't seem to tell me what the issue actually is. Here's the report.   Edit- Trying to get report, but copy paste being weird [22:59:59] [main/ERROR]:Error replacing mixin module source java.lang.ClassNotFoundException:

      I get this error when joining my 1.20.1 forge 47.4.0 / also tested on 47.3.39. It then shows a long list of mods and errors (see image). No crash occurs. https://cdn.discordapp.com/attachments/324493105313349644/1354950353665265824/image.png?ex=67e7275a&is=67e5d5da&hm=4006cb062aa548c3aff108082bf4ea5e44d6ead972da3b23102b74ea95f54c7c&
