Warum erstellen meine Netbeans kein neues Projekt?

Ich habe gerade NetBeans 8.2 installiert und alles schien gut zu laufen. Ich habe einen Standardwert von fast 100% vorgenommen, außer, dass ich ein oder zwei Module entfernte, die ich nie brauchen würde, und den Standardarbeitsbereich bei der ersten Ausführung geändert hatte.

Jetzt wird es nichts tun. Wenn ich auf den File->New ProjectBefehl klicke, passiert überhaupt nichts. Wenn ich auf mehrere andere Befehle klicke, passiert einfach gar nichts.

Das IDE-Protokoll zeigt eine Stapelablaufverfolgung, nachdem ich ein Projekt ausprobiert habe. Das ist diese Spur:
