Ran into an issue using Neoforge 1.21.1 and JDK 21. Anytime I try to run a python script it crashes and generates the below crash report.

I also added my Gradle dependencies to make sure I didn't mess those up.
`dependencies {
// compile against the JEI API but do not include it at runtime
compileOnly("mezz.jei:jei-${minecraft_version}-neoforge-api:${jei_version}")
// at runtime, use the full JEI jar for NeoForge
runtimeOnly("mezz.jei:jei-${minecraft_version}-neoforge:${jei_version}")

implementation("org.graalvm.polyglot:polyglot:24.2.2")
implementation("org.graalvm.polyglot:python:24.2.2")
implementation("org.graalvm.sdk:graal-sdk:24.2.2")
implementation("org.graalvm.truffle:truffle-api:24.2.2")

}`

This could all be a me issue but I wanted to make sure it isn't a problem with using this in a Minecraft environment.

You need to include the dependencies on the classpath. I don't know how that's handled in Minecraft. Or maybe you could try building a fatjar that would have all the dependencies included.
