Issue

It keeps showing an error

Reproduction Steps

  • Changed it to fabric

  • I don’t know if the files needs to be changed and I dont’ know how to do that I’m new to hosting

  • I know the GPU and GB were fine before this happened

    The error message says “Caused by: java.lang.UnsupportedClassVersionError: net/minecraft/bundler/Main has been compiled by a more recent version of the Java Runtime (class file version 69.0), this version of the Java Runtime only recognizes class file versions up to 65.0”
