SourceTree crashes on startup.

[Gary Kundel]

SourceTree crashes on startup. We're running Windows 10. This seems to be an issue with recent releases. Version 3.4.9 works. 

[Mukesh Kumar]

We have fixed this issue in Sourcetree 3.4.14 which will be available soon.

Currently Sourcetree 3.4.14 beta is available for beta users.

Hi,

Same issue, got a windows 10 update last night. I did try both https://community.atlassian.com/t5/Sourcetree-questions/Sourcetree-is-failing-to-start/qaq-p/2105728 solutions and none works.

[UPDATE] : Deleting all C:\Users\<UserName>\AppData\Local\Atlassian\SourceTree.exe_Url_[GUID] folders solved the issue in my case (not te SourceTree folder).

Hi @Joel Pellaud 

Some clients machines are throwing this error.

There is a JAC ticket related to this issue https://jira.atlassian.com/browse/SRCTREEWIN-13130. 

We are looking into this issue.

[Joel Pellaud]

Deleting all C:\Users\<UserName>\AppData\Local\Atlassian\SourceTree.exe_Url_[GUID] folders solved the issue in my case (not te SourceTree folder).

[Gary Kundel]

That worked!

[Mukesh Kumar]

Please find the log file and send it here from below path.

C:\Users\<UserName>\AppData\Local\Atlassian\Sourcetree\sourcetree.log

Log file can help us analyze the issue better.

[Gary Kundel]

As of late, I've instructed Desktop support to install 3.4.9 but we'll set up a test. I'll keep you posted. 

[Joel Pellaud]

I answered instead of replying here, sorry.

@Mukesh Kumar I think this is the same problem.

Seems persistent from 2019 bug. Please see if it can get fixed.  Thanks.

The error just happened for me. Unfortunately, your page won't allow me to paste the log file here. Paste is not an option and [Ctrl-v] causes the page to become unresponsive 

[Gary Kundel]

That said, Joel's solution worked. We still shouldn't be getting to this point.
