ArcGIS pro file paths seem to be made up and not exist in Catalog half the time. I can't seem to track down the directory path for my map to run a remove layer command on it. So I have to use Windows explorer and navigate to the project folder. Seems like Catalog on ArcGIS pro was a downgrade from 10.3+
All I am trying to do is remove a layer RemoveLayer—Help | ArcGIS for Desktop but it seems to be much more difficult in ArcGIS Pro than 10.3
