TheSourceTree cannot be opened

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?

Let us know if you found something out!

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?
