Hi, I can see this thread is quite old, but without answers, so here I am, trying to find a better solution for the same thing.
The issue is that for some unknown to be reason RSync is not working correctly when you have another ssh.exe visible in your path. What Is working for me is just searching for all ssh.exe’s and renaming them.
For example I have Windows 10 with Openssh module installed and a Git with it’s own ssh. When renaming them to something else this do work, but it’s not ideal solution.
From cmd you can find them by writing “where ssh.exe”.
Anyways give it a try as this can get you started.
