### Apache NetBeans version
Apache NetBeans 26
### What happened
On my system when opening Tools/Options and switching to Editor/Hints
following error is thrown:
```
java.lang.NullPointerException: Cannot invoke
"org.netbeans.modules.options.editor.FolderBasedOptionPanel.getSelectedLanguage()"
because "this.panel" is null

```
Options window then cannot be closed by close button or cancel button.
Checked and same or similar NPE is present in NetBeans 16, 25 and 27-rc1.
