SourceTree hangs on startup

[Aaron Wright]

Whenever I startup SourceTree it just hangs. All I get is a white window with a title bar. After some time it becomes unresponsive. I'm using Windows 10. I've uninstall and reinstalled SourceTree several times, but nothing changes.

This is such a vague problem, that my question is really, how can I start to debug SourceTree so I can at least figure out where to start looking?

Turns out I needed to uninstall and then delete the %LOCALAPPDATA%\Atlassian folder. Then, after reinstalling, SourceTree was much happier. So something in that folder was holding it up.

Logfile is at ${LOCALAPPDATA}\Atlassian\SourceTree\sourcetree-details.log , and contains nothing. Hows yours?

I'm having trouble opening Sourcetree after i updated to version 1.6.23, and is also using Win10. But i don't even get a white window. I will try to downgrade.

Thanks for pointing me at the right folder. Just needed to delete it.

Same thing happend to my 'Source Tree', hangs every time on startup.  Using the latest release (can't tell which release it is since the app always hangs).  deleted %LOCALAPPDATA%\Atlassian however, the app (after reinstall) still hangs after i re-added my repos.  Turns out deleting %LOCALAPPDATA%\Atlassian will remove all app settings (repos etc).  i will try going back to a really old version (that i know worked) and if that doesn't work i will look for some other tool, this is a bit too disruptive for me.
