Cannot start SSH Agent after Visual Studio 2017

[billwhitehead]

I installed Visual Studio 2017 which installed git.  This seems to have broken my ssh-agent in sourcetree now.  I tried to uninstall and reinstall.  Same thing.

The error I get is a window entitled "Error encountered".  The wording is "'ssh-agent' failed with code -1: System.NullReferenceException: Object reference not set to an instance of an object. ()"

Any ideas on what to do?  Should I try to uninstall the git update?

I finally found this link, https://community.atlassian.com/t5/SourceTree-questions/how-to-reslove-ssh-agent-failed-with-code-1-System/qaq-p/282052

I updated the embedded version of git, and that seemed to solve the ssh-agent issue.  

My problem now is SourceTree is still VERY unresponsive.  Not sure what happened.
