Odd numbered versions of NodeJS are not tested and are not explicitly supported. Please try with an LTS version (like Node 22 or Node 20)

Also, did you tick the checkbox to include all the necessary tools?

Unfortunately the node will not install with nodejs 22 either. It seems it is not compatible with the current nodejs versions. Also the node does not have a public source repository so there is nowhere to submit an issue against it.

You could try installing nodejs 20, but that will only be a short term solution unless the author updates the node.
