Hi Are you launching Burp using the standalone JAR file, or are you using the Windows Installer version of Burp? If you are using the standalone JAR file, the minimum version of Java that you will need to run Burp is Java 9. We would recommend using Java 16, as that is what our Installer version of Burp is packaged and tested with. Could you try redownloading Jython and specify the path to the new Jython standalone? You can find the Jython download here: https://www.jython.org/download.html

I'm using the current versions of burp and jython standalone, I had no problem installing Jhyton, but I can't use Python extensions. I have the same problem.
