I was unable to reproduce on the Windows machine I borrowed. Can you upload the installer you used?

Closed as duplicate of #22183.
It looks like the common problem is due to an NPE. Exception raised in EDT: java.util.concurrent.ExecutionException: java.lang.ExceptionInInitializerError. Ursache: java.lang.ExceptionInInitializerError. Ursache: java.lang.NullPointerException: Cannot invoke "javax.swing.JComponent.getInputMap(int)" because "org.openstreetmap.josm.gui.MainApplication.contentPanePrivate" is null. This is probably causing the class to fail loading, which in turn might be what is causing the NoClassDefFoundError.
