Aspose Words: JavaFX - Invalid License Signature Error

I’ve created two projects to use Aspose.Words 21.6 for Java.
One is a normal Java application and the other is a JavaFX project.
In the JavaFX project, I am receiving the following exception:

    Caused by: java.lang.ExceptionInInitializerError

	at com.aspose.words/com.aspose.words.zzWS3.<clinit>(Unknown Source)

The normal Java application does not receive this error and I’ve implemented the license the same way in both applications:

public static void main(String[] args) throws Exception {
   License license = new License();

To confirm that this error only occurs when using Aspose with JavaFX, I tested this with a new temporary license and created another JavaFX application and the error still persisted (it still does not occur in the normal Java application).

Any help on this would be greatly appreciated,
Thank you!
