Can not open the code file from node

I am trying to open the code of my Shader Graph masternode by RightClick → ‘Show Generated Code’, but I only get the error

InvalidOperationException: Cannot start process because a file name has not been provided.

What can I do to make the code open?

Hi,
Have you tried to reinstall your URP/HDRP (whichever you might be using) and Shader Graph too? Is everything else working ok in your project? Have you tried this in a fresh, new project?
