I had these issues but all it took was a visit to Java and download the remove old java tool and ran it
install java version 1.8.0_221
re point JAVA_HOME in the Control Panel\All Control Panel Items\System\advanced system settings\environment Vaiables. to the updated Java directory C:\Program Files\Java\jre1.8.0_221
Run Spoon.bat
all is well in the world.
