I deleted file "\AppData\Local\Atlassian\SourceTree.exe_Url_lt03l1ybxwq1qoho5ydpzegbicen0mbc\3.4.11.0\Composition.cache"

This resolved the issue for me and so far I have not seen any issues.

Hi Will,

Are you still experiencing this issue?

I've checked the log and I can see several mentions of Visual Studio, are you using Sourcetree with Visual Studio? Can you try wiping Sourcetree preferences and starting it again, and see if this time it works?

If you're still having issues, can you let us know which Sourcetree and Windows version are you using, so we can help you troubleshoot this issue?

Best regards,

Ana

I also have this problem. Has it been solved？

Danny Gorter

None of this worked for me. Apparently the folder names were mixed up. My executable is in AppData\Local\SourceTree\app-3.4.2 and the config of Atlassion appeared to be in \AppData\Local\Atlassian\SourceTree.exe_{ID}\3.4.2.0

I renamed the first folder to app-3.4.2.0 (so I added the 0) and then it started a fresh registration os Sourcetre. Did not complete this but killed it and changed the folder name back to app-3.4.2 and it started properly again.

Yep, I've tried your solution and works.

By the way I rename the folder back to origin name again and all the settings and repos keep the same.

And a prompt with temp files shown, I think this is the root cause why the source tree not loaded.

David Smith_o3b4da

This is the perfect fix!

For those who stumble across this with the same issue.

Last night I left my laptop on stand by with Sourcetree and Visual Studio open.

Windows decided to do a security update overnight so Sourcetree showed this exact issue in the morning.

I reversed the update but the corruption of the cache remained. Removing this file and relaunching the software resolved my issue as it rebuilt the cache with the new information.

I have logged a complaint with Microsoft as this looks like a .NET/Visual Studio issue caused by the changes in their update.

Thank you for the help Jonathan, absolute lifesaver!

Mauro Bertoli_t6x4rs

@Jonathan Folland thank you, life saver, it did work form me too. The same problem happened after a Windows 11 update. After the update and the reboot, Sourcetree 3.4.13 just shown his splash screen and then crashed.

To help others, you can just rename the file without deleting it.

Be aware that you need to find the folder with your current/latest version (as you can have many similar folders with different IDs) and rename `Composition.cache` to `_Composition.cache` and then start Sourcetree. A new `Composition.cache` file will appear.

Out of curiosity, I did compare the two (binary) files, and found out that the only change was related to the `Sourcetree` folder renamed in `SourceTree` 🤣
Ex:
before => C:/Users/[user]/AppData/Local/Sourcetree/app-3.4.13/

after => C:/Users/[user]/AppData/Local/SourceTree/app-3.4.13/

David Brady_3ut0n7

Thank you! Same thing happened to me. Windows 11 updated and then Sourcetree wouldn't load. And deleting the cache file fixed it.
