Why is it trying to listen on port 8? Can you configure the extension and set the port back to 8888 (the default) for example? Don't forget to press save.

Unfortunately, I cannot load the plugin, so I cannot modify the configuration either. Or you can tell me where to find the relevant configuration file.

Burp stores the settings for you, but I don't know where exactly tbh. The extension doesn't come with its own separate configuration file.

I can reproduce your issue by manually switching the port to 8 and then reloading the extension. This is probably a bug because the error should be handled more gracefully so you can still edit the settings afterwards instead of crashing completely.

FYI I'm currently prioritizing other projects so not sure when I can work on this. Feel free to have a look and create a PR, the Java error handling should be adjusted somewhere.
