     | The term 'npm' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

What steps can reproduce the bug?

Install something that is per user for example, npm under
npm@11.5.1 C:\Users\danie\AppData\Roaming\fnm\node-versions\v24.5.0\installation\node_modules\npm
