Can't generate C# script in Starter Assets

I’m using Unity’s first person starter asset, and I’m trying to generate a C# script out of the StarterAssets.inputactions file, but I continue getting an error saying “The namespace ‘global namespace’ already contains a definition for ‘Starter Assets’”. Any suggestions?

This simply means that an input action asset with the name “Starter Assets” already exists. You can delete the existing one and regenerate or rename it to something else. But, since it was already generated, why not just use it?
