Welcome to the forum @migkikas

As the error says, you need Python installed to build that node. I think that is included in the Windows Build Tools that the node red docs for windows tells you how to install.

I believe you need to run
npm install --global --production windows-build-tools
but I don't use windows so suggest you check out the link to the docs to check.

Solved!
