1. Run sourcetree
2. Dismiss error message
3. Go to system preferences -> Security & privacy
4. At the general tab, you should have message about blocked sourcetree, click "open it anyway"

Sourcetree should start.

I am also getting this error and do not feel like I should have to bypass the security issue from my OS. I need to run this software for my college course and really need help to figure out what is going on.

macOS Catalina version 10.15.5

Atlassian should fix the problem instead of compromising macos with a security issue.

Is there any answer to "fix the problem" on this issue?
