Sourcetree crashes with Git Flow features

Sourcetree on Windows 10 1803.

With a Git Flow enabled repo, any time I attempt to create a feature branch via the menu (Repository > Git-flow > Start New Feature) Sourcetree immediately crashes with a BugSplat popup. Note I am using Embedded Git v 2.24.1 with git-lfs v2.9.1. The repository configuration file has the [gitflow "prefix"], [gitflow "branch"], [gitflow "path"] blocks defined. Any ideas?

I have also the same issue but it is not happening consistently, it just crash about 1 times out of 5...

Hi, I am facing some similar issues with a curring project.


I was able to still create features by executing the command in the terminal instead of using the Sourcetree interface. Hope it helps

That same thing happens for me also!
