SourceTree crashing on launch

I am currently using Source Tree. I am using Mac 10.11.6. I have BitBucket setup on SourceTree. It unexpectedly crashed last time when I used it. But now I can't launch this application anymore. 

When I reopen SourceTree I get the error message "The last time you opened Sourcetree, it unexpectedly quit while reopening windows. Do you want to try to reopen its windows again?". Please see screenshot.

I tried clicking on both 'Don't Reopen' and 'Reopen' each option has the same outcome. The application just crashes as soon as it opens. I even tried to force quit and restart my Mac.

Same here. This all started just after I updated to macOS 10.13.5 (High Sierra).

Same problem.  Very frustrating.

I also have the same issue after upgrading to the latest version today.

Same Issue here. Log attached:

(note I'm still on 10.13.4 instead of 10.13.5 and it still crashes)

I'm having the same issue in a MacBook with the High Sierra.

I have the same issue. 

i also got this issue. How do i resolve?

I removed content from /Users/{USER_NAME}/Library/Application Support/SourceTree and then I installed a new version. Looks like it's working. 

yes, but that means you lose all your bookmarks. Have you tried adding bookmarks. After a few, it just starts crashing again

i just try, nothing happen

I added GitHub project works fine (pulling, pushing, etc.), are u adding Bitbucket project? I think the problem is with file

I tried this:

and continues crashing right after click Clone any repo i have in Bitbucket....

Can you update to version 2.7.1 and see if it helps?
If it crashes, please attach the crash logs to the ticket and we will investigate this.


Yes I already tried this. I deleted SourceTree and re-downloaded the latest version and the same problem occurred. The logs you see attached to that ticket is the latest version of SourceTree.
