[FIXED] How to fix IntelliJ Idea stuck on "Preparing WSL build environment..."?

Issue

I am using Ubuntu 22.04 with windows WSL, and have installed JDK 19.01 and Maven inside this, and have imported a file from the WSL into IntelliJ Idea to work on, however once I run a class, IntelliJ "builds" for upwards of half an hour, hanging on the messages of "Executing pre-compile tasks..." and "Preparing WSL build environment...". Obviously this is a pain and I need to know how to fix it.

I've tried to reinstall my JDK in Ubuntu and set the JAVA_HOME variable, which I've checked and have no issues with. I've tried to reinstall IntelliJ, and disabled my firewall/made exceptions, and I've changed the SDK being used inside IntelliJ, all to no success.

Here are logs from inside the Ubuntu terminal showing my JDK and Maven installations:

user@user  \~  mvn -v
Apache Maven 3.6.3
Maven home: /usr/share/maven
Java version: 19.0.1, vendor: Private Build, runtime: /usr/lib/jvm/java-19-openjdk-amd64

user@user  \~  echo $JAVA_HOME
/usr/lib/jvm/java-19-openjdk-amd64
user@user  \~  which java
/usr/bin/java
user@user  \~  which javac
/usr/bin/javac

Solution

Disable the real-time antivirus monitoring. It's a known issue.
