ENOENT: no such file or directory via "Open graph view" button

[Road-hog123]

If I click the Git Log button in the status bar the extension works fine, but if I click the "Open graph view" button in the Source Control panel (as I normally do) I get A system error occurred (ENOENT: no such file or directory, realpath 'C:\c:\Users\Nathan\Documents\Dev\Blender\blender') and the graph view does not open. This happens with any repository, even a freshly-initialised one.
