Hi,
Thank you for the screenshot.
You can manually type the version of your choice for Node.js and NPM in the CLI Tool Management preferences page for that project. Ensure that the versions being selected are compatible with the Angular CLI version of the project. You will see a warning message on the dialog in case the versions are not compatible. Apply the changes and close the dialog. Next go to the Terminal+ view and open a new tab by clicking on the + icon for the project and you will see the said versions being downloaded and your project will be updated.
Hope this helps. Please let us know how it works for you.
