Issue

Error: LinkageError occurred while loading main class net.minecraft.bundler.Main
	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
``` It keeps on giving me this message when I try starting the server in the console. I have no idea how to fix or what this does.

Reproduction Steps
--
 * I have tried adding code
 * I tried deleting the .jar files
 * I restarted and updating the instance
 * I created a new instance and hoped it would work
 * I used AI to help me
 * I changed the java versions and minecraft versions back and forth
