SourceTree suddently unable to start / crashes on Start

[Ben Griffiths]

Source Tree has suddenly stopped working. It has been working fine for ages, and this morning will simply not work.

It opens, shows the splash screen, briefly shows a "normal" SourceTree view and then quits (with no warning).

I have tried the following:

• Uninstalling and re-installing SourceTree (including installing an older version I have locally)
• Deleting various files (including everything) in:
  
  • AppData\Local\Atlassian
  • AppData\Local\SourceTree
  • AppData\Roaming\Atlassian

There are two errors in the event viewer:

The sourcetree.log file is below:

Any suggestions?
