I've followed the instructions on the README as well as on the Forge docs. I extract the MDK zip, open IntelliJ IDEA, import build.gradle, and it fails to build. I get the same thing everytime, both before and after executing `gradlew genIntellijRuns`, and it always errors at `Build model 'org.jetbrains.plugins.gradle.model.GradleExtensions' for root project 'forge-1.16.5-36.2.0-mdk'` It appears to be an issue with my IDE, right?

 

Here's the stacktrace
