Any ideas how to solve this other than uninstall / reinstall?

I updated Sourcetree yesterday, and now that it's updated, I am unable to open the application in Windows 11.

When I click the icon on my Desktop (or either .exe in the C:\Users\{me}\AppData\Local\SourceTree or specific version number directory \app-3.4.12), the app attempts to starts, I get the Icon splash screen for a second in the middle of my screen, but the app doesn't open. 

 

I'm going to try uninstalling + reinstalling since that seems to fix most of the problems I have. I guess the moral of the story is to never update.

 

The error below is from C:\Users\{me}\AppData\Local\Atlassian\SourceTree\sourcetree.txt

I have a similar problem.  Windows 11 update left Sourcetree not working.

I see that I now have source tree data in  C:\Users\harmo\AppData\Local\Atlassian\SourceTree

and C:\Users\harmo\AppData\Local\SourceTree.  I need a fix!

 

Sorry, not an answer
