SourceTree keeps crashing checking out a BitBucket branch

[donald_macleod]

I'm having problems with SourceTree crashing every time I click the "Checkout in SourceTree" button on a branch in BitBucket. SourceTree opens with a popup dialog to enter details for the Clone operation but once I set my destination folder (to a newly created empty directory) in the popup dialog and click the "Clone" button in the "Clone New" tab the app crashes.

Looking at Event Viewer immediately after the crash, the same unhandled exception appears in the logs (see below). I'm working on a 64-bit Windows 10 Pro OS, if anyone can help point me in the right direction on how to resolve this it would be much appreciated:-)

Application: SourceTree.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
