Final Checklist

• I have searched the issues and haven't found a similar issue.
• I have read the readme and know that what is action build.
• I have installed Fugue and it didn't fix my issue.
• I have installed Scalar Legacy and it didn't fix my issue.
• I have switched my Forgelin and LibrarianLib to continuous versions(check readme for more detail).
• I am running a test build from Cleanroom Github Actions. (Or, if I've compiled it myself I plan to fix the issue)
• I did not use PCL/PCLCE or other unsupported launchers.
  我没有使用 PCL/PCLCE 等其他未被支持的启动器。

Provide your log + crash report please

This mod uses the VanillaFix way to hack Loader and load mod mixins, but the Mixin it use is too old which end up calling a method non-exists in our Mixin
Will at least need a config blacklist feature to patch this...
