git difftool not working with files

git difftool not working correctly

Expected: ctrl-alt-d on file should open the difftool on that file. NOTE: ctrl-shift-D does open difftool on project
Actual: nothing happens

using winmerge. also, need to add the following to keymap.cson to get ctrl-shft-D to work:
'atom-workspace atom-text-editor:not([mini])':
'ctrl-shift-D': 'unset!'

 -0:00.0 bug-report:open (div.package-detail.panels-item)

1. Does the following command, executed from your working directory, open the difftool correctly?

git difftool --gui --no-prompt some/example.file

2. Does it open the file in your diftool correctly if you choose Git Difftool: Diff file from the command palette? (I believe it only opens for files that have changes not staged for commit, so make sure to test it with a appropriate file)

I have the same problem as described above.
Open on projects work fine, but not for files.
The command you proposed works fine in my git-bash
When typing the command in the the Atom Command line there is also no reaction.

Using
Atom 1.24.1 x64,
Git 2.16.2.windows.1
Windows 10 Pro
