  Description: The process was terminated due to an unhandled exception.

原因

The most likely reason for this error is that the user.config file for SourceTree has been corrupted.

You can confirm this by locating the file in this location:

C:\Users\<User>\AppData\Local\Atlassian\SourceTree.exe_<random_string>\<version_number>

If this is the cause, when you open the file, it will be full of <NULL> values.

ソリューション

If the user.config file is indeed corrupted, you may delete it.

It will be regenerated the next time you start SourceTree, and the application should start normally.
