Hi Chris25-56,

Thank you for taking the time to open an issue, it helps me to improve the extension.

It seems that your version of java is 1.8, you need a version 11 minimum.

I'm closing this issue, I encourage you to open another if necessary.

Edit: I advise you to install the correct version of java, to uninstall then reinstall all the extensions.
