Try uninstalling all the versions of Java you may have on your PC and then reinstall the latest version from Java’s website.

If its not that get back to me and we can try something else!

That did not work.

busted java install? uninstall java completely using oracles uninstaller, reboot, and then reinstall the latest version of java 8, ideally the JDK; You’re gonna wanna grab it from adoptopenjdk’s site for legal reasons
