SourceTree cannot be opened (Windows 10). Only Splash screen is shown temporarily and then nothing. Can someone suggest a solution?

Hi Mikhail,

welcome to the Atlassian Community!

Have you had the chance to look into logs?
Probably an error is logged there pointing to a possible cause?

https://confluence.atlassian.com/sourcetreekb/sourcetree-logfile-location-675384748.html

Let us know if you found something out!

Regards,
Daniel

I have the same issue/error and SourceTree stopped starting up, even after a system reboot. Any suggestions?

Uninstalling this Windows update got SourceTree to start properly again:

Atlassian - can you let us know when you get your software fixed so we can continue moving forward with Windows Updates?

Removing a windows update seems not secure enough

From my side I removed a folder with the name

C:\Users\<username>\AppData\Local\Atlassian\SourceTree.exe_Url_r3nh1lfhtz1f3pkvf1uaijkehygo5m2p
(figures can be different)

and the sourcetree starts again

I confirm this worked on my Windows 11 as well. I had two folders with that naming. Deleted them both and now it works fine. Thank you. I didn't uninstall any Windows updates.

Thanks for the solution @vhavard — deleting that second folder worked for me as well.

This did not work for me :(  My problem started around the same time.  The last time I opened SourceTree was over a month ago.  Today it won't open.

After deleting those folders the VS problems in the log have gone away but I still get a Failed to start with a different exception:

@Jon Thompson today I got the same issue again (I hadn't checked the logs to see if the root cause was the same as yours though). 

While I was trying to perform the same operation suggested by @vhavard above, SourceTree would still not open. Then I restarted Windows, and then it opened fine!

Unfortunately I never solved this.  I gave up and migrated to GitHub.  They have a tool which can import from BitBucket.
