Source tree crashing after pulling a repository (mac mojave)

[Charu Sharma]

Source tree is crashing every time I'm trying to open a repository window.Its working fine for another repository.

Tried uninstalling an installing source tree again again and deleted and pulled the repositories again.Source tree version is the lates one.Also there is no /Library/Application Support/SourceTree folder by default.

Attaching part of error report here because this is not accepting the whole crash report.
