Every time I load up Sourcetree, the app freezes for 20 seconds and unfreezes for an extremely short amount of time only to freeze again. I have tried installing different versions, yet nothing works. The only solution is to uninstall Sourcetree and reinstall it every time I want to use it, as the first time I open Sourcetree after installing it, it works fine If I close it and re-run it, though, it will begin to freeze/unfreeze.
