Sourcetree not responding when I try to commit after I changed my version of Unity

Hi everyone,

So my problem is the next : I recently changed my laptop and when reinstalling my softwares I choose to get the latest version of Unity. After that I tried to get back my in progress project and my repository on sourcetree but when I try to commit changes due to the new version of unity in my project, sourcetree just hangs and nothing more is happening.

I’m using Unity 2018.2.3f1 and sourcetree on windows 10.

Hope someone can help me, thanks for your time.

I tried to create a new repository and starting whith a commit of just the .gitignore filebut I got the same issue and Soucetree is not responding again.

Help ?
