Switch to Editor window leads to Netbeans crash

### Apache NetBeans version

Apache NetBeans 16

### What happened

I worked with Netbeans 8.2 and it had the same error as Netbeans 16. When i want to only show the editor by pressing a combination of Ctrl+Shift+Enter and try to navigate through project files netbeans crashes by showing an empty dark screen which i have to escape by closing it. I repeat it happened to all netbeans in my experience. Would be happy if it is fixed. However this happens some times randomly not all the time.

### Code of Conduct

Yes

Start by reproducing the crash in Apache NetBeans 16 on JDK 17: open a project, press Ctrl+Shift+Enter to show only the editor, and navigate through project files. Compare the behavior with NetBeans 12.6 or earlier and inspect the editor-window or project-file navigation path involved. Done means the editor view no longer becomes an empty dark screen or crashes.
