Hi @soerenbull - Welcome to the forums.

You might want to check your `settings.js` file - seems some modules have been prevented from being allowed to run

Welcome to the forum @soerenbull

I presume that error appears when you start node-red. Can you post the full output when you do that please, including the command line. Copy/paste not screenshot please. Use the `</>` button at the top of the forum entry window when pasting it in.

Check that file.

I think there is a section of `externalModules`, check here for any clue that may stop the module from running.

Maybe some of this `?

```auto
    externalModules: {
        // autoInstall: false, /** Whether the runtime will attempt to automatically install missing modules */
        // autoInstallRetry: 30, /** Interval, in seconds, between reinstall attempts */
        // palette: { /** Configuration for the Palette Manager */
        // allowInstall: true, /** Enable the Palette Manager in the editor */
        // allowUpdate: true, /** Allow modules to be updated in the Palette Manager */
        // allowUpload: true, /** Allow module tgz files to be uploaded and installed */
        // allowList: ['*'],

That is not a supported version of nodejs, you should stick to an LTS version, 16 or 18. I don't use Windows so I don't know how to do that. The node red getting started docs for Windows should tell you how you should install it.

How on earth did you install that ancient version? The current version of node-red-dashboard is 3.4.0.

That is all commented out, so nothing wrong there.  
Downgrade nodejs and install the latest version of the dashboard and I suspect you will be ok.

Upgraded dashboard. Everything works now.

Thank you!
