Currently, all Scala libraries will work as is if Scorge is used only for its extensions and not its language loader. However, using the language loader will always throw an InvocationTargetException.

Steps to reproduce:
Download the example mod provided with Scorge.
Set the corresponding build.gradle Scorge version to 3.1.2 and change Implementation to implementation.
Try to use any of the run* provided.

Reasoning:
In 1.16.2-33.0.30, cpw did a rewrite on how event dispatches are handled. As such, it ended up removing the field triggerMap which took in a consumed LifecycleEvent in favor of activityMap which now uses a Runnable. The problem with this is that triggerMap is still used as a field within ScorgeModContainer and will always error when ran.

This can most likely be fixed by supplying a runnable that constructs a new instance of the class as needed to the activityMap. Something potentially like this:

activityMap.put(ModLoadingStage.CONSTRUCT, this.constructMod)
...
private def constructMod(): Unit = {
    this.modInstance = modClass.newInstance().asInstanceOf[AnyRef]
}

Note that this example does not include any error checking or logging, just the minimum required to get it to run.
