Welcome to the forum @r-g0
From the errors:
npm ERR! gyp ERR! find Python You need to install the latest version of Python
So I think you need to install python. Did you install the windows build tools as described in the docs? I think that may install python as well as other stuff you may need but I am not certain.
Also Node version 16 is not yet supported by node-red. v14 is the most recent supported version. You might have problems with 16.
For the future you can paste logs directly here. See this post for how to do it - How to share code or flow json
